INTRODUCTION
With the development of advanced fiber reinforced composites as
viable structural materials the adhesive bonded joint has become of
primary importance. The bonded joint does not require that the stru-
ctural members being joined (adherends) be perforated to facilitate
bolts. Without the bolt holes and the stress concentrations associated
with. them, a substantial weight savings can be realized which is a major
reason for selecting composite materials for the structural component.
In order to fully realize the strength of the composite adherends,
the adhesive bonded joint must be efficiently desig;1ed and this requires
an adequate prediction of the stress distributions in the adhesive layer
of the joint. The study of stresses in the adhesive layer has been
approached by researchers in the past using one of two types of analysis
procedures.
Many researchers have attempted to predict the stresses using a
closed form analytical solution. However, when using this approach, the
equations that need to be solved become exceedingly complicated and this
leads to the need for simplifying assumptions. These assumptions have
included linearity, material isotropy, restrictions on the geometry of
the joint, and neglect of thermal effects.
Other researchers have approached the problem through the use of
numerical techniques such as finite element analysis. They have usually
found it necessary to use some or all of the assumptions made for the
1
2
closed form type solution procedure. The motivation for the present
study is to show the capability of a finite element computer analysis
program developed by Renieri and Herakovich [l] to adequately predict
these stress fields. The program has the capability for material ortho-
tropy, material nonlinearities, and temperature dependent properties.
Modifications to the computer program for this study include increased
element capacity, improved execution time, and capability for hygrother-
mal analysis.
Chapter 2
LITERATURE SURVEY
The first investigation into the behavior of bonded joints found in
the literature was presented in 1944 by Goland and Reissner [2]. They
obtained an analytical solution by assuming a state of plane strain,
prescribing the distributions of the shear and peel stresses to be
parabolic and linear, respectively, and applying restrictions on the
ratios of adherend moduli and thickness to adhesive modulus and thick-
ness. The solution is based on the principle of minimum potential
energy and is restricted to linear isotropic materials and identical
adherends. Thermal effects were neglected for this analysis.
Erdogan and Ratwani [3] approached the problem of an orthotropic
plate bonded to an isotropic plate with an isotropic ac'hesive. They
obtained closed form solutions for stepped lap and smocthly tapered
joints. Their solution was based on a su!TITiation of forces in the ad-
hesive layer and adherends and assumed plane stress anc linear material
behavior. This sol·Jtion predicted stress singularities at the edges of
each step in the ad~esive in the stepped lap joint, anc at the ends of
the overlap in the adhesive for the smoothly tapered jcint.
Barker and Hatt [4] used a linear elastic finite element computer
analysis program to compare results with the work of Erdogan and Ratwani
[3]. The adherends were modeled using four noded isoparametric elements
and material orthotropy was considered. The adhesive layer was modeled
using a special element developed for that purpose which was formulated
3
4
to have no thickness and used modified stiffnesses derived from the
moduli, thickness, and length of the adhesive layer. Their results
compared favorably with Erdogan and Ratwani.
Sainsbury-Carter [5] solved the stepped and linearly tapered
bonded joints by assuming linear isotropic materials and solving the
equations of equilibrium. It was assumed that the moduli of the adher-
ends are much larger than those of the adhesive. Also the analysis was
one-dimensional and thermal effects were neglected. It was shown that
the thickness of the adherends greatly affected the magnitude of the
peak shear and peel stresses and an iterative technique was developed to
modify these thicknesses within stress design criteria.
Wah [6] investigated non-symmetric single lap joints with composite
adherends and isotropic adhesives. Laminated plate theory was used to
develop stress and moment resultants and relcte them to mid-plane
strains and curvatures. The laminated adhercnds were required to be
mid-plane symmetric in order to uncouple the bending-stretching terms in
the previously mentioned relationships. A solution was presented for
the joints under shear loadings as well as axial loads. The solutions
were restricted to the elastic range and thermal effects were neglected.
Hart-Smith [7] was the first researcher to consider the non-lin-
earity of the adhesive layer by assuming its stress-strain response to
be elastic-perfectly plastic. This effort presents solutions and
design aids, including thermal effects, for single, double and stepped
lap joints and linear tapered joints. While a thermal mismatch is
considered all material properties are considered temperature indepen-
5
dent. This research notes the increased failure strength by allowing
for plastic deformation in the adhesive.
A comparison of theoretical and experimental shear stress in a
single lap joint was presented by Sharpe and Muha [8]. The joint
modeled had plexiglass adherends and an epoxy adhesive. Good correla-
tion was obtained with the work of Goland and Reissner [2] and with a
linear computer analysis program, BOND4, of the University of Delaware.
Renton and Vinson [9-10] performed parametric studies on single lap
joints as well as fatigue testing and thick adherend lap shear testing.
The specimens were comprised of mid-plane symmetric composite adherends
and elastic behavior only was studied. Linear thermal effects were also
included. The parameters studied were over-lap length, adhesive thick-
ness, and ply orientation in the composite adherends. Comparisons were
made with the work of Goland and Reissner [2] with Renton and Vinson's
work showing better satisfaction of stress free boundary condition at
the edge of the adhesive layer.
Grimes, Greimann et al [11] approached the analysis of single,
double, and stepped lap joints from both the finite element method and
numerical integration of the governing differential equations. Their
analysis included full material nonlinearity in the adherends and
adhesive layer. The development for both solutions was based on the
deformation theory of plasticity with the finite element analysis
utilizing an iterative procedure until the solution converged. In both
forms of analysis, solutions were presented for room temperature only
and curing stresses were neglected.
6
DasGupta and Sharma [12] used an analysis similar to Goland and
Reissner [2] to predict stresses in lap joints with prebent adherends.
The work showed a decrease in peak stresses with the use of bent ad-
herends.
Renton [13] provided an analysis of the thick adherend lap shear
test using the work of Renton and Vinson [9-10]. This research verified
the validity of the test.
Other researchers have investigated the effects of moisture [14],
and the reliability [15] of lap joints.
While this survey is by no means all-inclusive, it is representa-
tive of the research that has been performed and from this survey the
need for fully-nonlinear mat2rial behavior and temperature dependent
properties can be seen as these physical realities have been consis-
tently neglected.

BASIC CONSIDERATIONS
The bonded joints selected for analysis in this study are single
and double lap joints with and without adhesive layers. Typical geo-
metries for joints with adhesive layers are shown in Figure 1. Composite
and isotropic adherends are considered with nonlinear material properties
and thermal stresses as well as temperature dependent properties.
Hygro·scopic analysis capabilities are presented but no results are
included in this investigation due to a lack of complete consistent
data.
3.1 Geometric Restrictions
For the present study it is assumed that the joint is in a state of
plane strain (i.e. Ex= 0, or Ex= const). This is a valid assumption
if the x dimension of the joint (Fig. l) is 1arge and the cross-section
under consideration is some distance removed from contraints that are
dependent upon the x coordinate.
The analysis is also restricted to balanced, mid-plane symmetric
composite adherends and laminate material properties are used for these
components.
3.2 Quasi 3-Dimensional Analysis
The analysis of reference [l] co~siders a long prismatic bar under
the influence of a uniform applied strain or temperature change to have
strains independent of the x coordinate. With this assumption, the

strain displacement relations can be written as

_ au + aw _ f ( ) _ au + av _ f ( ) y xz - al ax - 5 y ,z ' y xy - ay ax - 6 y ,z
where· u, v, and ware x, y, and z displacements, respectively, and f1 through f6 are unknown functions of y and z coordinates only. With the
use of suitable mathematical manipulation, (3.1) can be integratec yield-
ing the following form for the displacement fields
u(x,y,2) = x(C1y+C2z+c3) + U(y,z)
2 v(x,y,z) = x(C4z+C6) - c1 ~ + V(y,z)
2 w(x,y,z) = x(-C4y+C5) - c2 ~ + l~(y,z)
(3.2)
where c1 through c6 are unknown constants and U, V, and Ware unknown
functions of y and z only. With this assumption, and ne~lecting body
forces, the equilibrium equations can be written as

3.3 Bonded Joints
The analysis developed in [l] can be used as two different formula-
tions for the solution of bonded joints. The first of these corresponds
to a classical plane strain solution in which £ = y = y = 0. This x xz xy type of solution is entirely 2-dimensional and i~; the type of plane
strain analysis used in a majority of joint analyses previously in the
literature.
The second formulation is a more general plane strain solution
where Ex ; 0 but is equal to some constant ~x· For this procedure the
components of strain Yxz and Yxy are assumed to be zero. The principal
difference between the two formulations is that the second accounts for
the transverse stiffness (Ex) of the adherends and adhesive while the
first does not. This second formulation is used for this analysis and
comparisons between results obtained fron, the two solutions are pre-
sented in Chapter 5. In the following sc!ctions and chapters the first
formulation is referred to as a 2-dimens;onal formulation while the
second is referred to as a quasi 3-dimen;ional analysis as it corresponds
closely to the analysis of section 3.2.
3.3.l 2-Dimensional Joint Formulation
In the classic plane strain solutio(1 the displacements, strains,
and therefore stresses, are independent •)f the x-coordinate (Fig. 1).
Under these assumptions the displacement fields (Equ. 3.2) reduce to
u = 0
v = V(y,z)
w = W(y,z)
(3.4)
11
The nonzero strain components (ey' ez and Yyz) have the same definitions
as in Equ 1 s. ( 3. l ) .
3.3.2 Quasi 3-Dimensional Joint Formulation
If, in a bonded joint, it can be assumed that ex is a nonzero con-
stant and that Yxz and Yxy are zero, then the displacement fields
(Equ's. 3.2) reduce to
u = s x x v = V(y,z)
w = W{y,z)
(3.5)
In these equations the only nonzero constant from Equ's. (3.2), c3, has
been renamed sx and corresponds to the uniform normal strain ex. The
remaining strain components (ey' ez, and Yyz) again have the same form
as in Equ's. (3.1).
The assumption that the strain comp< nent normal to the plane Jf the
analysis is constant is strictly valid f•,r the case of single lap
joints with identical orthotropic adhere; ds. It is also valid for
double lap joints where the outer adhere;:ds are identical and exhibit
orthotropy. The assumptions that Yxz = Yxy = 0 are valid if the
adherends are orthotropic.
The restriction that all adherends be orthotropic is satisfied
by all joints analyzed in this study. It should be noted however
that two of the joints analyzed do not satisfy the first condi-
tion as they are single lap joints with differing adherends.
12
For these joints, the solution n.eglects the effects of bending out of
the plane of the joint and is similar to a membrane solution in this
respect.
3.4 Material Properties
In order to adequately model a layered adherend layer by layer an
excessive number of finite elements would be needed. Because of this,
it is necessary to use laminate material ~roperties and consider the
composite adherends to be homogeneous orthotropic materials for the
joint analysis.
Obtaining laminate material properties from the literature proved
to be impossible thus making it necessa~· to generate these properties
analytically. For this generation of priperties two different approaches
were used. The stress-strain response o = a laminate was predicted
following the work of Renieri and Herako1ich [l], while thermal proper-
ties were predicted using classical lamination theory.
3.4.l Prediction of Laminate Stress-Strain Response
The details of the analysis of ref. [l] will not be presented as to
do so would be overly repetitious; however a brief outline will be pre-
sented for completeness.
The analysis utilizes the displacement fields of Equ's. (3.2).
Because the laminates in question are balanced and midplane symmetric
the analysis can be reduced to the quarter section shown in Figure (2b)
with certain symmetry and anti-symmetry conditions. The displacement

fields (Equ's. 3.2) reduce to
u = ~xx + U(y,z)
v = V(y,z)
w = W(y,z)
(3.6)
and again the constant c3 has been renamed ~x and corresponds to a uni-
form applied strain. The displacement fields (3.6) along with the stress-
free boundary conditions along the free edges, top and bottom surfaces
and certain restrictions imposed upon the displacements by the symmetry
and anti-symmetry conditions mentioned previously represent the boundary
value problem to be solved by the finite element analysis. With this
analysis and the nonlinear finite element program, the moduli Exx and
EYY can be predicted as functions of strain level.
3.4.2 Prediction of Laminate Thermal Properties
Laminate thermal properties including coefficients of thermal ex-
pansion and moduli as functions of temperature are predicted using
lamination theory and unidirectional material properties as functions
of temperature. Lamination theory as presented here cannot directly
predict temperature dependent laminate properties, however, if the uni-
directional properties used as input correspond to an elevated tempera-
ture, then the laminate properties generated will also correspond to
this temperature. Therefor~, laminate properties can be predicted at
discrete temperatures corresponding to the input data.
The constitutive relations for a single, orthotropic lamina in the
principal material coordinates are

where the principal coordinates are shown in Fig. 2a as the 1-2-3 system.
These equations can be written in an abbreviated form as
(3.8)
For a coordinate rotation about the 3 axis through an angle e (Fig. 2a)
the stresses and strains are transformed according to the following
relations,
{cr}x = [T1]{cr}1 and {e:}x = [T2]{e:J1 (3.9)

Combining Equ's. (3.8) and (3.9) yields
{cr}x = [T,J[CJ[T2]-1{E}x
or
fo} = [c]{d x x (3.10)
where [CJ is defined as
[CJ = [T1J[CJ[T2J-1 (3.11)
and has the form

Equ's. (3.10) are the coristitutive relations for an orthotropic lamina
rotated through an angle e.
For lamination theory it is assumed that a lamina is in a state of
plane stress. It should be noted that this lamination theory development
is the only case in which plane stress will apply while plane strain is
assumed in all other developments.
The mathematical statement of the plane stress assumption is
a = T = T : Q z xz yz (3.13)
which can be used to reduce the constitutive relations (Equ's. 3.7) to
=
0
0
0 (3.14)
This simplified form of the stiffness matrix [CJ is known as the reduced
stiffness matrix [Q]. If the transformation matrices (Equ's. 3.9) are reduced similarly, a
rotated plane stress constitutive relation [Q] can be formed in the
same manner as Equ's. (3.10). Thus

Now, taking the standard plate theory assumption that normals to
the mid-plane of the plate remain normal after loading, the strains of
Equ's. (3.15) may be written as

Now define laminate coefficients of thermal expansion such that
{e 0} = {a}t.T (3.29)
where 6T is a uniform temperature change and
Combining Equ's. (3.18), (3.22), and (3.29), and considering symmetric

When the moduli and thermal coefficient~ used to calculate the [CJ
matrix (Equ's. 3.7) are those corresponding to an elevated temperature,
then the moduli of Equ's. (3.25) and coefficients of expansion of Equ's.
(3.31) will be laminate properties also corr~sponding to that tempera-
22
ture. These reduced moduli will be used as input in the finite element
program.
These methods of generating material properties were resorted to
because of the lack of consistent experimental data found in the
literature.
3.5 Finite Element Formulation
As in section 3.2.l the presentation of the complete formulation
would be a duplication of the work of Renieri and Herakovich [l],
therefore only the highlights will be given here.
The finite element solution process involves the subdivision of a
structure into a finite number of smaller elements (Fig. 3). This
process is known as discretization. For each of these finite elements
a set of interpolation functions are chosen tc represent the displace-
ments at any point in the element as functions of the displacements at
the corners or nodes of the element. Using the strain-displacement
relations (Equ. 3.1) the strains can also be calculated as functions of
nodal displacements. Now with the use of a variational principle, such
as the principle of minimum potential energy, a set of equations re-
lating nodal forces to nodal displacements can be obtained for each
element,
(3.32)
where {F} = nodal forces
{u} = nodal displacements
[K] = element stiffness matrix
23
8 ELEMENT

(b) DOUBLE LAP JOINT

24
and the superscript (2) refers to the individual element. These elemental
relations (Equ's. 3.32) are then combined or assembled into a larger
system of equations relating forces to displacements for the entire
structure. The solution of these equations yields the displacements and
therefore the strains and stresses over the entire body.
The finite element scheme developed by Renieri and Herakovich [l]
utilizes the constant-stress, constant-strain triangular element with
three nodes. The interpolation functions used are
(3.33)
As can be seen from the form of Equ's. (3.33) these are linear relations
and will yield constant strains when substituted into Equ's. (3.1). The
constants a1 through a9 are functions of the spatiitl coordinates and
nodal displacements of the individual elements and ~x is the applied
uniform strain.
Manipulation of Equ's. (3.33) and substitution into Equ. (3.1)
yields the following strain-displacement relations for an element.
25
e:x E; A x e:y av1 + cv2 + ev3 e:z l bw1 + dw2 + gw3 (3.34) - A 'Yyz bv1 + dv2 + gv3 + aw1 + cw2 + ew3
Yxz bu1 + du2 + gu3
Yxy au1 + cu2 + eu3
where A = area of the element
u, ' u2' u3 = x-displacements at nodes l ' 2, and 3 respectively
v, ' v2' V3 = y-displacements at nodes 1 ' 2' and 3 respectively
wl' w2' W3 = z-displacements at nodes 1 ' 2, and 3 respectively
and a, b, c, d, e, g are known constants involving spatial coordinates
only.
For the case of a uniform thermal load the strains are
{e:}l = {e:*}1 - T { e: } l (3.35)
where {e:*} l = to ta 1 strain
{ e:}l = mechanical strain
and T { e: } l = thermal strain
which consists of {a}1 (Equ. 3.26) multiplied by the temperature change
~T. Transforming Equ's. (3.35) to an. arbitrary coordinate system yields
an individual element.
(3.36)
26
Noting Equ 1 s. ( 3. 34) , these strains can be written as
2 2 e:x i; - (m a.1 + n o.2)6T x
(av1 + cv2 + ev3)/A - 2 2 E:y ( n a.1 + m a.2)6T
e:z (bw1 + dw2 + gw3)/A - a.36T ( 3. 37) =
Yyz (bv1 + dv2 + gv3 + aw1 + cw2 + ew3)/A
Yxz (bu1 + du2 + gu3)/A
Yxy (au1 + cu2 + eu3)/A + 2mn6T(a1-a.2)
The preceding formulation for thermal strains is completely analogous
for that of hygroscopic strains. For an orthotropic material the coef-
ficients of hygrosopic expansion are
~:,
f;2
{ rn 1 = 83
(3.38) 0

Following exactly the development of Equ's. (3.35) through (3.37) and
substituting {S}l for {a.}1 and 6M for 6T where 6M is a uniform percent
weight change due to moisture absorption or desorbtion, yields
27
e:x sx - (m2sl + n2s2)AM
E:y (av1 + cv2 + ev)/A - (n2Bi + m2s1)AM

Yxz (bu1 + du2 + gu3)/A
Yxy (au1 + cu2 + eu3)/A + 2mnAM(B1-s2)
The hygroscopic expressions are presented here because the capability
for this type of analysis has been included in the computer program.
Results will not be presented because of the lack of data as stated
earlier. It should also be noted that the derivation is for a uniform
temperature or moisture change and that analysis should be limited to
cases where uniformity is a valid assumption.
The principle of minimum potential en2rgy states that a body is in
equilibrium when the total potential energy$ is minimum where
(3.40)
Ue = internal strain energy
and
We = potential energy of the applied loads
The internal strain energy for an element is
(3.41)
which for an element with constant strains and unit thickness reduces
to
28
(3.42)
In both Equ's. (3.41) and (3.42) the strains involved depend upon whether
the loading is mechanical (Equ's. 3.34), thermal (Equ's. 3.37) or
hygroscopic (Equ's. 3.39). The potential energy of the applied loads is
given by the negative of the applied forces multiplied by their respective
displacements.
Minimization of Equ's. (3.40) with respect to displacements yield
the elemental stiffness matrix plus strain, thermal and hygrosopic re-
lated vectors. The forms for these can be four.d in Appendix A.
3.6 Boundary Conditions for Joints
The boundary conditions applied to single and double lap joints for
the present study are shown in 1=i g. 3. A number of dif Fe rent boundary
conditions and loadings were in~estigated and compariso~s were made.
These are summarized in Table 1. Noting Table 1 it is seen that
all conditions except the fourth yield comparable results. The lower
peak stresses for this condition can be attributed to an overly flexible
model. It was reasoned that this does not correspond to physical reality
as a real joint would not be free to deflect up and down where the load-
ing is applied. The first set of conditions was eliminated from consider-
ation as they can only be applied to symmetric single lap joints. The
second set was eliminated becau~e during the solution process a negative
diagonal in the global stiffness matrix was encountered. The third set
of conditions was disregarded b~cause the stress distribution in the

adhesive layer was not symmetric for a symmetric joint while it is in-
tuitively obvious that it should be. The fifth set of constraints and
loading was chosen because it provided symmetric results, numerical
stability and is applicable to nonsymmetric joints.
3.7 Qualifying Notes
Due to the lack of data present in the literature a number of
assumptions concerning material properties have been made. For lamina
data input, it is assumed that E22 is identical to E33 . It is also
assumed that the three shear moduli G12 , G13 and G23 are identical.
Poisson ratios are considered constant and percent modulus retentions
are assumed identical in tension and compression
When inputting laminate material properties, much of the data is
generated according to the analyses.presented earlier. It is assumed
that the 02
-£2
laminate response is identical to the 0 2-£ 2 response of
a unidirectional lamina. It is also assumed that the 'yz-Yyz and
'xz-Yxz curves are the same as the , 12-y12 response of a lamina and
that the laminate poisson ratios vxz and vyz are the same as the lamina
poissons ratios v 13 and v23 , respectively. Other restrictions are the
same as for lamina data.
It should be mentioned here that the material properties used in
this analysis (Appendix C) are not consistent. The data has been taken
from a number of sources and is not all realted to identical material
systems. Even with these limitations it is felt that the investigation
still fulfills its goal of showing the capability to analyze joints if
consistent properties were available.
Chapter 4
NONLINEAR ANALYSIS
A significant portion of the research effort involved in this study
was devoted to the modification of the finite element analysis program
NONCOM [l]. The improved version, NONCOMl will be briefly described
here.
4.1 Modifications of NONCOMl
For the analysis of bonded joints, a number of modifications to the
existing finite element program were implemented. These included:
(1) Increased finite element capacity
(2) Inclusion of a more efficient equation solver
(3) Capability for input of fully 3-dimensional orthotropic
material properties
Other modifications included:
(4) Capability for hygroscopic analysis
(5) Capability for elevated temperature and moisture
content analysis
4.1.1 Increased Finite Element Capacity
In order to model an adhesive bonded jcint a large number of finite
elements are needed because of the large stress gradients and inherent
large aspect ratio of the adhesive layer. r:or this reason the maximum
number of elements was increased from 100 tc 400 elements. This was
done with an increase of high speed storage of approximately 50 percent.
31
32
This increase was held this low through the use of storage addressing
schemes where many arrays are stored in the same col'Mlon storage loca-
tions and by the block storage schemes of the equation solver chosen.
4.1.2 Solution of Simultaneous Equations
The equation solver in NONCOM is not suitable for large systems of
equations as its solution time becomes excessively large for such
systems. For this reason a new equation solver, SESOL [16] was selected
for NONCOMl. This equation solver offers a fast solution time and high
speed storage reduction schemes. In brief the solution algorithm
considers the system of linear equations
[K]{X} = {R} ( 4.1)
where [K] is the assembled stiffness matrix, {X} is the nodal displace-
ment vector and {R} is the applied nodal load vector. The stiffness
matrix is factored into an upper and lower triangular matrix
(4.2)
where [G] is upper triangular and [L]T is lower triangular and normalized
such that Lii = 1 (i not summed). Since [K] is symmetric
G •• = G •• L. . ( i not summed) lJ 11 lJ
and equation (4.2) can be written as
[K] = [L]T[D][L]
(4.3)
(4.4)
where
[DJ =
Defining
G •• 11
33
(i not summed)
{V} = [D][L]{x}
and combining equations (4.1) and (4.6) yields
(4.5)
(4.6)
(4.7)
The vector {v} in equation (4.7) is first found by Gauss reduction of
the load vector and then the nodal displacements are found through back
substitution into equation (4.6). The stiffness matrix and load vector
are assembled and stored on low speed storage in block form as in Fig.
4. During the solution process, reductions are performed on non-zero
terms only and only two blocks need be in high speed storgage at any
time.
In the computer program NONCOMl the number of equations per block
is determined as a function of the maximum half oandwidth plus the
diagonal of the assembled stiffness matrix. This is done to minimize
the number of blocks necessary and maximize the number of equations per
block within high-speed storage limitations. By making the number of
blocks a minimum, I-0 operations performed by the computer· with the
elemental stiffness matrices are also minimized. To further this re-
duction ~f operations the blocks are assembled two at a time.

It should be noted the size of the maximum half bandwidth plus
diagonal is not only a function of node numbering, as is usually the
case with the finite element analysis, but is also a function of the
type of loading applied. When the applied loading is thermal, hygro-
scopic or an average force applied in the x direction an equation re-
lating a uniform strain to an average force in the x direction is
required in addition to the equations relating nodal forces and dis-
placements. This equation is related to all of the elements and may
involve all the nodal displacements of the finite element model. To
minimize the effect of this equation on the maximum half bandwidth plus
diagonal it is assembled in the center of the stiffness matrix. The
average force equation and its effect on the bandwidth can be seen in
Fig. 4 where the T's represent the average force terms. The half band-
width plus diagonal without the average force equation is shown by the
dotted line. These two bandwidths are for identical finite element
models under.different loadings.
4.1.3 Three Dimensional Properties
The program NONCOMl was given the capability for fully three
dimensional orthotropic material properties because of the restriction
that composite adherends must be modeled as homogeneous orthotropic
laminates (Chapter 3). This means that a plane of transverse isotropy
cannot in general be assumed as done in NONCOM [l].
4.1.4 Hygroscopic Analysis
A capability for hygroscopic loadings has been included in NONCOMl.
36
It is modeled in the computer program in exactly the same fashion as the
thermal analysis and is therefore subject to the same limitations. The
most notable of these is the restriction that the moisture distribution
be uniform throughout the finite element model. Other restrictions will
be mentioned in the section dealing with the nonlinear analysis.
4.1.5 Elevated Temperature and Moisture Content Analysis
This modification allows for mech~nical loading at elevated tempera-
ture and moisture content or thermal loading at elevated moisture
content or hygroscopic loading at elevated temperature. Insight into
the interactions between thermal and hygroscopic material response could
not be obtained from the literature. For this reason two assumptions
are made about these interactions. First, it is assumed that hygro-
scopic properties are independent of temperature and that thermal proper-
ties are independent of moisture content. It is also assumed that
changes in mechanical properties due to temperature and moisture content
are cumulative. By cumulative it is meant that when a modulus is to be
modified to correspond to both temperature and moisture content it is
first modified for the temperature and then this new modulus is then
modified to correspond to the moisture content. The process of changing
material properties will be more fully described in the following section.
4.2 Nonlinear Analysis
In order to simulate nonlinear material behavior in a computer
program with the linear elastic finite·elerrent analysis described in
Chapter 3 two separate problems must be dealt with. First a method of
37
accounting for material nonlinearities within the analysis procedure and
second a method of representing the nonlinear material properties.
4.2.l Incremental Loading Procedure
The finite element computer program NONCOMl deals with varying
material properties through the.use of a incremental solution procedure.
With this type of procedure, the load whether mechanical, thermal, or
hygroscopic is applied as a series of increments. This yields a series
of linear solutions with total stresses, strains, and displacements
formed by sunmation of the linear increments of these quantities. When
applying the load incrementally the material properties are updated to
correspond to the current levels of strain, temperature, and mositure
content. With the finite element method an individual element can have
material properties varying independently of other elements in the
model.
4.2.2 Nonlinear Data Input
Material stress-strain response for an othrotropic material in the
principal material coordinates are represented in the form of modified
Ramberg-Osgood [17] approximations which have the form
a K n. E = E + icr l i = l or 2 (4.8)
In equation (4.8) E is the elastic modulus and Ki and ni are Ramberg-
Osgood coefficients. A method for calculating the four coefficients K;
and ni is described in Ref. [l]. A tangent modulus can be defined as

It can be seen in Fig. 5 that the strain £~-O for which the tangent
modulus is calculated differs from the strain £p ~here the modulus
should be calculated. This difference is a function of the size of the
load increment and can be made negligible by choosing an appropriately
small increment. For the computer analysis it is assumed that the shear
response is independent of sign while ~xtensional behavior can be
different in tension and compression.

thermal and hygroscopic expansion as functions of temperature and
moisture content respectively. During thermal or hygroscopic loading,
the moduli and coefficients of expansion are calculated at the mid-point

program it is assumed that percent modulus retentions are identical for
tension and compression.

RESULTS AND DISCUSSIONS
The analysis procedures presented in Chapters 3 and 4 were used to
generate laminate properties and analyze various bonded joints. The
joints investigated included single and double lap joints with, and
without adhesive layers. Both elastic and non-linear results are pre-
sented. The material systems considered were graphite-polyimide, boron-
epoxy, titanium, and aluminum for the adherends, and Metlbond 1113 and
AF-126-2 for the adhesives.
5.1 Materials Properties
The mechanical and thermal properties for the materials used in
this study were taken from the literature whenever possible. However,
as was stated in p~evious chapters,·complete properties were not always
available for a given material system. Therefore, laminate properties,
with the exclusion of uni-directional laminates, were predicted in
accordance with the analysis procedures presented earlier and the
results can be found in Appendix C which contains all of the material
properties of this study.
5.2 Averaging of Finite Element Results
The finite element analysis presented in Chapter 3 is based upon a
displacement formulation. This approach yields results in the form of
displacements at the node points and stresses and strains which are
constant over each element. Because the stresses are constant for an
41
42
individual element, a distribution of stresses over a series of elements
may appear to be discontinuous. In many cases, however, it is known
that the stresses must be continuous. For this reason, stress averaging
was used to produce the desired smooth distributions.
Noting Fig. 6a, stresses are presented along the line A-A which
corresponds to the mid-plane of the adhesive layer. The stresses pre-
sented at point E would correspond to an average of the stresses in
elements 3 and 4. This method of averaging was used for all joints with
adhesive layers.
When considering bonded joints without adhesive layers, the stresses
in question are along the interface between the two adherends. This
interface is shown as line C-C in Fig. 6b. For the stresses 'yz and
a2
which must be continuous across the interface: the results presented
correspond to an average of elemental stresses above and below the inter-
face. Thus, these stresses at point G would consist of an average of
elements 13, 14, 21, and 22. The normal stress components ax and cry are
not necessarily continuous across this interface so these stress
components are averaged along both line B-B, and line D-D. At point F,
an average of element 11 and 12 is presented and at point H, the stresses
are averaged between element 19 and 20.
The stress components 'xy and 'xz have not been mentioned as they
do not occur either at the mid-plane of the adhesive layer in adhesive
bonded joints, nor at the interface between the adherends in non-
adhesive bonded joints since the adherends in this study, when composite
laminates, are considered to be homogeneous, orthotropic materials. If

these components were present it could easily be shown that Txz must be
continuous across an adherend-adherend interface while Txy would need not
be.
5.3 Finite Element Representations
For the analysis of bonded joints, t~o finite element models were
used. Fig's. 7 and 8 sl1ow partial plots of the finite element models of
joints with, and withou·: adhesive layers, respectively. Both of these
models were generated u·;ing a mesh generator described by Bergner, Davis,
and Herakovich [18]. In both figures the scaling of the model for the
figure is not uniform. In Fig. 7, the aspect ratio of an element in the
adhesive layer ranges from 2.5 at the fre£ edge to 15 at the center of
the adhesive layer. The aspect ratio's o~ the elements in the adherends
range from 1.1 to 9.0. For the joints without adhesives (Fig. 8) all
aspect ratios are 1.0.
5.4 Stress Free Temperature
Bonded joints are, in general, cured with a combination of elevated
temperature and pressure. The maximum temperature involved in this
process is known as the cure temperature. The temperature at which
curing stresses begin to form is the stress free temperature and, in
general, the cure and stress free temperatures are not the same. The
stress free temperature of th~ adhesives used in this study was chosen
to be 270°F. This value was selected because both adh2sives are epoxy
based and 270°F was the value used in [l] for epoxy matrix material
systems.

For bonded joints without adhesives, the stress free temperature
was chosen to be 350°F. This is the value reported in [19] as the
stress free temperature of graphite-polyimide laminates. This is ap-
propriate as polyimides were the only composite lamiantes used in joints
without adhesives.
5.5 Linear Elastic Results
This section contains the linear thermoelastic results for various
joints. The dimensions for adhesive bonded joints are shown in Fig. 1.
For joints without adhesives the dimensions are identical to those of
joints with adhesives except the adhesive layer is removed. Most of the
curves in this section were drawn by the VPI & SU computer plotter.
In the figures that follow the superscripts M ard T are used to
differentiate stresses. Mechanically induced stresses are indicated by
the superscript M while thermal, or curing, stresses are denoted by the
superscript T. These are also used in combination irdicating a super-
position of mechanical and curing stresses. In some instances a curing
stress is referred to, while the corresponding figure presents only the
mechanical, and combined mechanical and curing stresses. The magnitude
of the curing component can, of course, be determined by taking the
difference of the combined, and mecranical stresses.

loading consists of a thermal increment of -200°F and an applied dis-
placement. The resulting stresses are shown to t/L = 0.5 as the stresses
are symmetric about this line.
Upon examination of Fig. 9 it is seen that the stress free boundary
conditions
cr I = 0 and • I = O y t/L = 0 yz t/L = 0 (5.1)
are not satisfied by the finite element solution. This is due to the
nature of the constant stress finite elements used and the limitations
on the maximum number of element available. In order to check the
finite element analysis 1 ability to meet such stress free boundary
conditions, an analysis was performed on a small portion of the adhesive
layer from t/L = 0.0 to t/L = 0.05. The displacements predicted along
the upper and lower interfaces of the adhesive in the joint solution
were used as loading for the partial adhesive analysis. The stress
distributions produced by this analysis exhibited the proper trends
with crz reaching a peak value near t/L = 0 and cry and Tyz tending
towards zero. These distributions are not presented, however, as they
appeared very erratic. It is believed that this was caused by round-
off error in the applied displacements. This error may have become
significant after subtracting rigid body motion from the joint analysis
displacements.
In order to check the validity of the finite element solution
presented in Fig. 9, a number of static equilibrium calculations were

made. The equilibrium equations for one half of a single lap joint
corresponding to the free body diagram of Fig. lOa are
EF = 0 = V - Rb' y 1
EF = 0 = N - R z 1 a'
and (5.2)
The finite element program NONCOMl does not back substitute the nodal
displacements to solve for the nodal forces. Therefore it is not
possible to determine the reactions Ra or Mb. However, the reaction Rb
can be determined as the average of the cry stresses of the elements
adjacent to the edge where Rb acts multiplied by the adherend thickness
and assuming a unit depth. A compa~ison )f v1 and Rb determined from
the finite element solution indicates a four percent error as shown in
Table 2.
Since the unknown reactions severely limit the equilibrium calcula-
tions for the previous joint, similar calculations were also performed
on a more simply constrained joint. This joint corresponds to the joint
shown in Table 1, condition 4, and a free body diagram of one half of
the joint is shown in Fig. lOb. For this free body diagram the equili-
brium equations are

As in the previous joint, the reaction moment Md cannot be determined
from the finite element solution. However, by removing the constraint in
the z direction, the integral of the oz stresses, N2, must now equal zero.
The results of these equilibrium calculations are also shown in Table 2.
Returning to Fig. 9, it can be seen that under mechanical loading
only~ the shearing stresses dominate the stress fields. This is a
function of the overlap lenth, L. If the overlap were longer, for a
given loading, the shearing stresses would be reduced while the peak
a~ stresses would increase. This will be shown later in the section
containing nonlinear results and can be verified by considering the
force and moment equilibrium equations (5.2). It is interesting to note
that the normal stresses cr~, a~, and cr~ are very close in magnitude for
this joint.
Since the stresses presented are produced by the displacements of
the joint, its deflected shape would provide significant insight into
the physics of the problem. Fig. 11 shows the deflection of the upper
edge of the lower adherend under mechanical loading only. The dashed
line signifies the beginning of the overlap (2 = 0). In this figure
it is difficult to distinguish any curvature of the adhere~d in the
region of the overlap because of the relatively small distance involved.
A plot of the overlap only showed a nearly straight line distribution
also indicating very little bending in this region. It is interesting

that the maximum bending occurs just before the overlap region. However,
due to the layout of the finite element model, which was designed for
adhesive studies, the stresses in this high bending region cannot be
accurately obtained.
Again returning to Fig. 9 it is seen that the only nonzero components
of curing stresses are o~ and o~. Actually, the finite element solution
did predict other components of curing stresses but their magnitudes
were insignificant. It is difficult to make a valid comparison of the
relative magnitudes of the mechanical and curing stress components as
the mechanical loads were produced by a small load increment while the
curing stresses are due to the full temperature change from the stress
free temperature to room temperature. The a; curing stresses represent
approximately 15 percent of the ultinate strength of the adhesive and
while this magnitude is not exceedingly large, its contribution should
be included in a failure theroy.
5.5.l.2 [0/±45/90]s Graphite-Polyimide Adherencs
Fig. 12 represents the mechanical and curing stresses for a single
lap joint with [0/±45/90]s graphite-polyimi de adherer,ds and Metl bond
1113 adhesive. The loadings are identical with those of the previous
joint. Comparing Fig's. 9 and 12 it can be seen that under mechanical
loading only, the magnitude of the peak adhesive strEsses decrease with
decreasing adherend stiffness EY. Thus, for the samt~ loading, the joint
with [OJ adherends has higher stresses than the joint with [0/±45/90]s
adherends. However, when considering curing stresses, this is no longer
the case. It can be seen that the magnitudes of the stresses o~ and

a; are larger for the [0/±45/90]s joint than for the [OJ joint. This
is due to the effects of the transverse stiffness and coefficient of the
thermal expansion. For the [0/±45/90]s adherends the longitudinal (y)
and transverse (x) directions have identical modulus and coefficient of
expansion. This quasi-isotropy leads to curing stresses, a~ and
a~, that are identical for the joint with [0/±45/90]s adherends. This
is not the case for the joint with [OJ adherends as the transverse
direction has a much lower modulus and higher coefficient of expansion
than the longitudinal direction.
Because the adherends of this joint have identical transverse and
longitudinal stiffness it is appropriate to determine what effects the
transverse stiffness have upon the mechanically induced stresses. For
this purpose the joint of Fiq. 12 was also loaded under a classical
plane strain assumption. The resulting stresses are shown in Fig. 13.
The loading and materials were identical for both joints except that for
the joint of Fig. 13 the average normal stress acting perpendicular to
the plane was not specified and the strain normal to the plane, Ex' was
zero. Also, ax stresses are not presented for the classic plane strain
solution. Comparing the two figures (12 and 13) it can be seen that the
mechanically induced stresses are reduced slightly for the quasi three-
dimensional analysis. This indicates that a 2-D solution would under-
estimate the strength of this joint. Comparisons of the stress com-
ponents for the two joints can be found in Table 3. The curing stresses
are identical for the two joints because both analyses were performed
under the 3-D analysis.

5.5.1.3 [90] Graphite-polyimide Adherends
The mechanical and curing stresses of a single lap joint with [90]
graphite-polyimide adherends and Metlbond 1113 adhesive are shown in
Fig. 14. Comparing Figs. 9, 12, and 14 the trends pointed to earlier
concerning adhesive stresses and adherend stiffness are again confirmed.
It is seen that the [90] adherends produce the lowest mechanical stress-
es of the three joints. Comparing Fig's. 9 and 14 only it is revealed
that the a! curing stresses for the [OJ joint are identical to the cr~
stresses for the [90J joint. This is as would be expected and the same
correspondence is also seen between the cr~ of the [90J joint and the cr~
of the [OJ joint.
5.5.1.4 [OJ and [90J Graphite-Polyimide Adherends
The adhesive stresses for a single lap joint with [OJ and [90]
graphite-polyimide adherends and Metlbond 1113 adhesive due to mechani-
cal loading only are presented in Fig. 15. The most striking aspect of
these stresses is the lack of symmetry present in their distributions.
This is due, of course, to the unsymmetric nature of this joint. It is
also interesting to note that the peak values of stress occur near the
line i/L ~ 1.0 This correspondence of the peak stresses with the more
flexible adherend seems inconsistent as the trends of the previous
joints pointed to higher stresses with stiffer adherends. This can be
explained upon examination of Fig. 16 which presents displacements of
the upper adherend-adhesive interface relative to the displacements of
the lower adherend-adhesive interface. The displacements are normalized
with respect to the thickness of the adhesive layer. It can be seen

that the relative displacements vr (y-component) reach a much higher
value at t/L = 1 than at t/L = 0, while the wr displacements (z-com-
ponent) are nearly symmetric about the center of the joint (t/L = 0.5).
The normalized component v can be considered as a shear strain thus in-r . dicating why the shearing stresses are much larger near ~/L = l in Fig.
15. It is interesting that the wr component is nearly symmetric. This
indicates that bending is not a major factor. This corresponds to the
results seen in Fig. 11 where the curvature of adherend was nearly zero
in the overlap region. From Fig. 16 it is seen that the increased
stresses are due, almost entirely, to the increased flexibility (EY) of
the [90] adherend.
Returning to Fig. 15 a discontinuity in the cr~ stress distribution
can be observed at t/L = 0.2. This can be explained as a change in
adherend stiffness corresponding to a change in the finite element
representation of the adherend. Referring back to FiJ. 7, this change
in representation is seen as the point at which the adherend in the
model is changed from two, to one layer of elements. This situation was
unavoidable due to the large number of elements required to model the
adhesive layer and a limitation on the maximum number of elements
available. This change in stiffness is recognizable in many of the
stress distributions presented for adhesive bonded joints.
Curing stresses for the single lap joint with [O] and [90] ad-
herends are presented in Fig. 17. These stresses are, not surprisingly,
different than those for the joints presented earlier. For this case,

present due to cure. From observing the '~z and a~ distributions it can
be seen that the integrals of these stresses appear to be zero, as would
be required by equilibrium considerat1ons. It is interesting to note
the magnitude of the '~z stress peaks near t/L = 0 and t/L = 1. The
values of shearing cure stresses are nearly 75 percent of the ultimate
shear strength of the adhesive. Because the mechanical and curing
stresses have opposite signs near t/L = l it can be seen that curing
counteracts the large mechanical stresses in this region. It should be
mentioned, however, that the percent modulus retentions, used for de-
termining moduli as functions of temperature, are only strictly valid
through a limited portion of the stress-strain curve of a material.
Because of this, the peak shear cure stresses may not be quite as ac-
curate as the other components of cure stress which correspond to points
lower on their respective stress-strain curves.
5.5.2 Double Lap Joints with Adhesives
5.5.2.l [OJ Graphite-Polyimide Adherends
The adhesive stresses due to curing and mechanical loading for a
double lap joint with [OJ graphite-polyimide adherends and Metlbond 1113
adhesive are presented in Fig. 18. Here, as with the single lap joints,
the mechanically induced shearing stresses don:inate the mechanical
stresses. It is interesting to note the lack of symmetry present in
these stress distributions due to the restrictions upon the w displace-
ments along the midsurface of the inner adherend. These restrictions
are induced by the symmetry of joint about the midsurface of the inner

adherend. Comparing Fig's. 9 and 18 it can be seen that the mechanically
induced stresses are smaller for the double lap joint than for the
single lap joint. The distributions are more uniform for the double lap
joint indicating reduced bending in the adherends. This is also due to
the restrictions on the w displacements.
The curing stresses for this double lap joint follow the trends
exhibited by the single lap joints where the adherends were identical,
with oT and oT being the only significant curing stresses. As expected, . x y the magnitudes of the curi_ng stress compo11ents are i dent i ca 1 to those of
the single lap joint with [OJ adherends.
5.5.2.2 [90J Graphite-Polyimide Adh' rends
Fig. 19 represents the curing and mechanical loading induced stress-
es of a double lap joint with [90J adherends. Co1,1paring Fig's. 18 and
19 it is seen that the peak stress values decreas~ with increased flexi-
bility of the adherends, as was the case with sir gl e 1 ap joints. Nati ng
the curing stresses of both of these joints it c11n be seen that the
o~ cure stresses are higher for the [90J adherencl joint while the o~
cure stresses are higher for the [OJ adherend joint. This is exactly
the same as with the single lap joints and the reason for it is also the
same.
5.5.2.3 [OJ and [90] Graphite-Polyimide Adherends
Mechanically induced adhesive stresses of a double lap joint with
[OJ and [90] graphite-polyimide adherends and Metlbond 1113 adhesive are
represented in Fig. 20. As was the case with the two previous double
lap joints, comparisons made with a single lap of the same adherends

(Fig. 15) shows lower peak stress values and a more uniform distribution
of stresses for the double lap joint. A striking similarity between
these two joints is the location of the peak stress values corresponding
to a line near t/L = 1.0. In the double lap joint, as in the single
lap, this is due to the increased relative displacement vr at the line
t/L = 1.0. It is interesting to note that the restrictions on the
displacements in the z direction in the double lap do not greatly de-
crease the relative difference in peak stresses near t/L = 0 and t/L =
1.0 in comparison to the single lap joint, indicating that the effects
of bending are also small for the double lap joint.
The curing stresses for this double lap joint are presented in Fig.
21. This figure shows that the cr~ curing stresses are very small while
the '~z stresses are approximately 90 percent of the ultimate shear
strength. Comparing these stresses ·to those for a single lap joint of
the same adherends (Fig. 17) indicates that for curing stresses, the
restrictions.upon displacements at the midsurface of the inner adherend
in the double lap joint are not necessarily hc~lpful. The double lap
joint produces higher shearing stresses, but ·1ower peel stresses than
those of the single lap joint. The only difference between the two
joints is the increased bending stiffness of the inner adherend in the
double lap. This indicates that bending stiffness is an important
factor in these curing stresses. This must also be the cause for
differences in the cr~ and cr~ curi.ng stresses of the two joints.

Before presenting the first set of results in this section it should
be pointed out once more exactly how the following stresses were
averaged (see section 5.2). For the case of stresses which must be
continuous across the interface between the adherends, the stresses pre-
sented are an average of the elemental stresses above and below this
interface. For stresses which need not be continuous, the results
presented consist of elemental stresses averaged either above or below
the interface, thus two crx and cry curves are presented for each joint.
This will also be the case for the stress results in the next section.
5.5.3.l [OJ Graphite-Polyimide Adherends
Fig. 22 presents the interfacial stresses of a single lap joint
with [OJ graphite-polyimide adherends and no adhesive. These stress
distributions are interesting in that the shear stress Tyz is not the
dominant stress as it was in the joints with adhesives. For this joint
it is seen that the cr~ upper and lower stres,;es are of greater magni-
tude and that cr~ attains higher peak values :han the shearing stresses.
For this joint T~z appears to be nearly unif )rm along the interface at
a relatively low value. Due to the strength of the [OJ laminates in
the fiber direction it would appear that failure would initiate as a
result of the peel stresses a~.
Curing stresses are not presented for t1is joint as they do not
exist. The finite element solution was also checked on this point with
the results being zero as required.

with [90J graphite-polyimide adherends are presented in Fig. 23. These
distributions show the same trends as the previous joint with the o~
upper and lower stresses being the largest, o~ reaching a relatively
high peak, and T~z showing a nearly smooth distribution. Comparing
Fig's. 22 and 23 it is seen that the larger stress values occur with the
stiffer adherends as was the case for all of the adhesive bonded joints
in previous sections.
5.5.3.3 [OJ and [90J Graphite-Polyimide Adherends
Fig. 24 is a plot of interfacial stre~ses for a joint with [OJ and
[90J graphite-polyimide adherends under mechanical loading. As with the
previous two joints, the internal stresses o~ upper and lower are the
largest in magnitude. It is interesting tc' note that for this joint the
peak stresses do not necessarily occur with the more flexible adherend,
as was true for adhesive bonded joints. For this joint o: and o~ lower have peak values near ~/L = 0 while ~~z and cr~ upper have peaks
near t/L = 1.0. Further examination of Fig. 24 indicates that the
internal stresses are highest in the direction of the fiber in these
unidirectional laminates. Thus o~ is larg=r for the [OJ adherend than
in the [90J adherend while o~ is larger for the [90J adherend.
Curing stresses for this joint are presented in Fig: 25. The
magnitudes of the o~ stresses in the [OJ adherend are nearly 60 percent
of the ultimate strength of laminate which represents a significant
curing stress. The a; curing stresses in the [90J adherend are also
large at 40 percent of ultimate. The other internal components of

stress oT upper and oT lower are of comparable numerical value, but are x y in the fiber direction of their respective adherends and therefore do
not represent such significant percentages of the ultimate strengths.
This figure shows that equilibrium appears to be satisfied by the o~
and T~z curing stresses.
5.5.4 Double Lap Joints without Adhesives
·Fig's. 26 and 27 represent mechanically induced interfacial stress-
es fo~ double lap joints with [OJ and [90J graphite-polyimide adherends
respectively. These joints show higher st)~esses with the stiffer adher-
ends as with all other joints presented. It can be seen that with these
joints the a~ stresses are the largest as has been shown for all joints
without adhesives.
Comparing Fig's 22 and 26 it can be seen that the double lap joint
has higher stresses for the same displacemc~nt loading. This can only be
caused by the increased bending stiffness of the inner adherend in the
double lap joint. This trend is also presEnt in comparison of Fig's. 23
and 27 representing joints with [90J adherends. For joints with ad-
hesive layers the effect of the increased bending stiffness of the inner
adherend was to smooth and reduce slightly the stress distributions for
double lap joints in comparison to single ·1ap joints.
Fig's. 28 and 29 represent the mechanical and curing stresses
respectively for a double lap joint with [OJ and [90J graphite-polyimide
adherends. As with the single lap with [OJ and [90] adherends and no
adhesive, the peak stresses for mechanical loading do not occur with the

for lap joints with adhesive layers. The curing stress components cr~
for the [O] adherend and o~ for the [90] adherend represent approxi-
mately 60 percent of ultimate strength for the laminates.
5.5.5 Elastic Loading Comparisons
After reviewing the stress distributions of the four previous sub-
sections, interesting comparisons can be made by considering the force
loading corresponding to the displacement applied for each of the joints.
The results can be seen in Table 4. In this table the force load for
double lap joints corresponds to the total load carried by the joint.
The forces for all of the joints are calculated by averaging stresses in
the elements at the ends of the adherends, m11ltiplying by the thickness
of the adherend, and assuming a unit depth.
Making comparisons of single and double lap joints with the same
adherends it can be seen that the double lap joints carry more than
twice as much force as the single lap joints. In the cases where the
joints have adhesives, this can be seen as a beneficial effect of the
increased bending stiffness of the inner adh1~rend, as the peak stresses
for double lap joints of this catf~gory are lower than for the single lap
joints. The increased load carrying capacity is due to the more uniform
shear stress distribution of the double lap joints, which creates a
larger resultant force opposing the load.
Comparisons of single and double lap joints without adhesives also
show a more than doubled load carrying capacity for the double lap

double lap joints making it unclear as to which joints are the more
efficient.
5.6 Nonlinear Results
Bonded joint stress distributions presented in this section were
predicted using the analysis of Chapter 3 and the nonlinear formulation
of Chapter 4. Mechanical and thermal loading was applied as a series of
increments. Where curing stresses are presented, they correspond to
the total curing load. Mechanically induced stresses are presented at
three load levels for each individual joint. The load levels for an
individual joint do not necessarily correspond to those of other joints.
The dimensions of the joints of this section are identical to those of
the elastic results (Fig. 1) except. where otherwise stated.
5.6.1 Single Lap Joints
5.6.1.l Lap Shear Test
The adhesive shear stress and strain distributions for a lap shear
test joint with aluminum adherends and Metlbond 1113 adhesive are shown 1 'A f ( I
in Fig's. 30 and 31 respectively. This joint corresponds to that used i)- ! j;.
in Ref. [20] for determining the adhesive shear properties as used in
this study. The dimensions of this joint are presented in Table 5. 11

These two figures (30 and 31) point to the 1~ffects of the nonlinear
shear behavior of the adhesive. Examination of Fig. 30 reveals that as
the displacement loading increases, the shEar stress distribution
becomes more uniform. Fig. 31, however, shows that the shear strain

distribution does not become more unfiorm as loading increases. This
can be explained by considering the shear stress-strain response of the
adhesive (Appendix C, Fig. C.6). The slope of this curve becomes much
smaller as the strain is increased. Therefore, in the bonded joint, the
increment of stress corresponding to an increment of strain, at high
strain levels, is smaller than at low strain levels. Thus, the shear
stress distribution in the center of the joint is increasing more
rapidly as loading increases than at the edges (t/L = 0 and t/L = 1),
because the strains are higher at the edges. It is interesting to note
that the largest shear stress presented (Fig. 30) is nearly a constant
value. This value corresponds to the ultimate shear strength of the
adhesive.
As was stated earlier, this joint corresponds to a joint used in
the lap shear tests [20]. Therefore, comparisons between numerical and
experimental work were made and the results can be found in Table 6 and
Fig. 32.
The experimental stresses and strains presented in Table 6 are
values corresponding the maximum stress of the adhesive shear curve.
These stress and strain values are chosen for the comparison because of
the nature of both the Ramberg-Osgood [17] approximations, and the
finite element analysis. The Ramberg-Osgood parameters cannot model the
stress-strain curve beyond the point at which the slope becomes zero and
the finite element formulation does not produce a positive definite
stiffness matrix when a negative modulus is used.
In Table 6, the numerical strain chosen for the comparison was near

the line i/L = O. This is also the region where the strain was de-
termined in Ref. [20]. This table shows good correlation between ex-
perimental results and the numerical prediction. In Fig. 32 two finite
element stress-strain responses are presented. In both of these finite
element curves, the stress corresponds to an average of elemental
stresses throughout the adhesive layer.
The upper numerical curve (AVE.F.E.) presents strains that are also
aver~ged over the entire adhesive layer. The lo~er numerical curve
(F.E. STRAIN NEAR i/L = 0, AVERAGED STRESS) shows strains corresponding
to the finite elements adjacent to the line i/L = 0 in the adhesive.
The upper curve shows a better stress correlation while the lower curve
shows a better ultimate strain correspondence with experimental data.
Fig's. 33, 34, and 35 present the cr~, a~, and a~ adhesive stresses
of the same lap shear test joint under identical loadings. These
figures do not show the effects of adhesive nonlinearity in such a
pronounced fashion as Fig. 30. The reason for this is two fold. First,
the extensional stress-strain response of the adhesive is not as non-
1 inear as the shear response. Secondly, the extensional stress values
produced are not as large in magnitude relative to the ultimate strength.
The maximum crz and cry stresses correspond to approximately 15 percent of
the ultimate while the maximum ax component is approximately 10 percent
of ultimate. Upon examination, Fig's. 34 and 35 reveal the discon-
tinuity at ~/l = 0.2 that was discussed in the elastic results (section
5.5.1.4). Thermal stresses are not presented for this joint as they
would have no bearing on the comparisons made. This is because the

shear properties produced from the experimental work on this joint [20]
included any effects of curing.
An interesting comparison can be made concerning results obtained
from the two different solution formulations presented in Chapter 3. In
order to produce similar stress and strain distributions, it was neces-
sary to apply a larger displacement load to the joint analyzed under the
quasi 3-dimensional formulation. The additional load corresponded to
1/15. of the total displacement applied for the 2-dimensional solution.
The resulting ultimate force loads were identical for the two analyses
indicating that under the quasi 3-dimensional formulation the joint was
more flexible and therefore capable of withstanding a larger displace-
ment load.
5.6.l.2 [0/90/0/90/0] Boron-Epoxy Adherends and
AF-126-2 Adhesive
This adhesive bonded joint was selected for analysis in order to
compare the results of this study to those of Ref. [11]. For this
comparison it was necessary to use a force loading instead of the dis-
placement loading used for all other joints in this study. The force
loading was required in order to exactly match the loading in [11]. In
[11], two solution procedures are used. In the first, an iterative
finite element analysis is used to account for material nonlinearities.
The second procedure utilizes direct numerical integration of the
governing differential equations for the joint. Results obtained by the
second procedure are labeled as theoretical in the following figures.
The dimensions of this joint are given in Table 5.

Fig's. 36 and 37 present the adhesive stress components <~z and
a~ respectively. In Fig. 36 it can be seen that the distributions of
the shear stresses predicted by the present study compare favorably with
the two distributions predicted in [11]. The principal difference is
seen to be the magnitude of the peak stresses near the lines t/L = 0 and
t/L = 1. It is interesting that none of the shear stress distri-
butions presented in Fig. 36 satisfy the stress free boundary condition
<yz ~ 0 at t/L = 1. It appears that the areas under each of the three
curves are approximately the same as required by equilibrium considera-
tions.
In Fig. 37 it can be seen that the cr~ distributions predicted by
the present study and theoretical results of [11] have significant
differences. The present analysis predicts a symmetric distribution of
peel stresses while the theoretical results [11] .show peak stresses at
t/L = 0 and t/L = 1 differing by more than 100 percent. The nonsym-
metric nature of these results appears physically inconsistent as the
adherends are identical. The finite element results presented in [11]
do show the symmetry of stresses as predicted by this study. Another
interesting aspect of the theoretical results is the reversal in sign of
the peel stresses near t/L = 1.0. This is not seen in the finite
element results of this study or [11].
Comparisons of the numerical values of the peel stresses cannot
realistically be made as the extensional properties of the AF-126-2
adhesive were not known. The extensional Ramberg-Osgood coefficients
used for this adhesive correspond to the extensional properties of

Comparing Fig's. 36 and 37, it can be seen that for all solutions
except the finite element solution of [11], the peel stresses are
larger than the shear stresses. This verifies the statement made about
the effects of the overlap length, L, upon the magnitudes of the shear-
ing and peel stresses in an earlier section (5.5.1.1). For this joint,
with a large adherend overlap, the peel stresses are dominant with
resp~ct to maximum value. If the magnitudes were compared with respect
to ultimate strengths however, it is believed that the shearing stresses
would again dominate. It is not known what these ultimate strenths are
however, and therefore this comparison cannot be made.
The curing stresses for this joint are presented in Fig. 38. As
was shown for the elastic results, the only significant curing stresses
are a! and a;. This is again due to the identical adherends and the
material properties of the adherends and adhesive. It is interesting
that even though the values of the curing stress components a~ and a;z are insignificant, they reach peak values n£arly an order of magnitude
larger than in any other joint with identical adherends. Since these
curing components (a~ and T;z) are negligible, the stresses presented in
the previous two figures (36 and 37) can be considered either mechanical
or combined mechanical and curing stresses.
The magnitudes of the curing components a~ and a; with respect to
the ultimate extensional strength of the adhesive is not known because
as was stated earlier, this ultimate strength is not known. The analy-
ses of [11] ignore the effects of curing, and while this does not affect

the az and Tyz stress components, it can be seen that curing is signi-
ficant in the two components of stress not presented in [11] (ax and
cry).
Fig's. 39 and 40 present the combined mechanical and curing stress-M+T M+T . es, cry and ax of this joint. These distributions reveal that the
curing stresses (Fig. 38) are of the same sign as the mechanically in-
duced stresses and therefore would be detrimental to the performance of
the joint under tensile loading.

Nonlinear curing stresses for this joint are not plotted as the
significant components (a~ and a~) are uniform throughout the adhesive.
The numerical values for these stresses can be found in Table 7. This
table presents a comparison between.elastic and nonlinear results for
this joint. For these curing stresses, the elastic solution under-
estimates the a~ and a~ components by 10 percent and 5 percent respec-
tively.
The mechanical loading of this joint was analyzed utilizing the 2-
dimensional formulation (Chapter 3). This was done because for this
joint, the two formulations produce negligible differences in the stress M M M components cry, az, and Tyz' The similarity in results is due to the
relatively small difference in magnitudes of the adherend transverse
stiffness (Ex) and the adhesive extensional stiffness. Combined mech-
anically and curing induced adhesive stresses are presented in Fig's.

shearing stresses for this joint (Fig. 41) exhibit nonlinear effects.
Comparisons between elastic and nonlinear mechanically induced stresses
are presented in Table 7. These comparisons show that the cr~ and
a~ stress components behave linearly throughout the range of mechanical
loading applied. The shearing stress is decidedly nonlinear though,
with the elastic solution predicting stresses 82 percent higher than the
nonlinear results indicate.
5.6.l.4 [±45]s Graphite-Polyimide Adherends and
Metlbond 1113 Adhesive
The nonlinear curing stresses for this joint are not plotted for
the same reasons as the previous joint. The numerical values of the two
significant curing stresses are presented in Table 8 which presents a
comparison of elastic and nonlinear results for this joint. This
comparison shows a six percent increase in the curing stresses for the
nonlinear analysis.
Combined mechanical and curing adhesive stresses for this joint are
shown in Fig's 44, 45, 46 and 47. Again, it is seen that nonlinear
behavior is present in only the shear stresses. It is unfortunate that
the maximum loading for this joint did not produce a peak shear stress
corresponding to the ultimate strength. This would have produced much
more pronounced nonlinear effects. Comparisons between elastic and
nonlinear mechanical adhesive stresses are also presented in Table 8.
It is seen that at the maximum load level attained, the nonlinear
results predict a peak shear stress 28 percent below the elastic re-
sults. The elastic mechanical results are determined as the first

increment of the nonlinear results scaled to the maximum displacement
load. It is somewhat surprising that the nonlinear analysis does not
predict lower stress components a~, a~, and a~ for this and the previous
joint. It can be explained however by considering the final magnitudes
of these stress components. All are relatively low on the extensional
stress-strain response of the adhesive. At these stress levels the
curve is very linear resulting in very linear stress predictions.
5.6.2· Double Lap Joints
5.6.2.l Titanium Adherends Metlbond 1113 Adhesive
Comparisons of elastic and nonlinear curing stresses for this joint
are shown in Table 9. Once more, the two nonzero components of curing
stress (a~ and a~) were uniform and they are not plotted. Here again,
an increase in the nonlinear results over the elastic case is seen.
Combined stresses for this joint are presented in Fig's. 48, 49, 50
and 51. In these figures only the shear curves show pronounced non-
linearities, as before, but Table 9 indicates that the other stresses
(ax, ay, and az) are slightly reduced for the nonlinear analysis. The
reason this joint should exhibit nonlinear behavior where the previous
joints did not is not immediately discernable. The most obvious dif-
ference between this joint and the previous ones is the restriction
placed upon the w displacements at the midplane of the inner adherend by
the symmetry of the double lap.

distributions appear very similar to the elastic curing stresses for the
same joint (Fig. 21). Comparisons between these two analyses are shown
in Table 10. It can be seen that the nonlinear curing stresses differ
from the elastic results between 2 percent and 6 percent. The 23
percent difference shown for crz near t/L = 0 is probably exagerated by
the low magnitudes of these stresses. It can be seen in Table 10 that
the nonlinear effects cause an increase in the cr~ and cr~ curing stresses
as shown in previous results. However, the a! and T~z stresses are
decreased by the nonlinear behavior. These two stresses are related
through equilibrium (section 5.5.1.1) and it is therefore appropriate
that both change in the same fashion. This decrease is due to
the high values of shear stress produced by curing and the low adhesive
modulus at these values.
Fig's. 53, 54, 55, and 56 present combined mechanical and curing
adhesive stresses for this joint. Comparing Fig's. 52 and 53 it can be
seen that the curing stresses are very beneficial to the performance of
this joint. In Fig. 53, as the displacement load level increases, the
shear stresses near t/L = 1 are seen to increase more rapidly than at
t/L = O. Thus, the shear stresses near t/L = 1 would be much larger
than the shear stress near t/L = 0 for mechanic.al loading only. Ho1 1-
ever, the curing shear stresses near 1/L = l have the opposite sign of
the mechanical shear stresses in this region and are of relatively large
magnitude. Therefore, a large portion of the mechanically induced shear
stresses are negated by the curing shear stress and thus the joint is
capable of carrying an increased load.

Chapter 6
SUMMARY AND CONCLUSIONS
The present analysis has been concerned with the nonlinear analysis
of bonded joints. Upon reviewing the results presented, the following
conclusions can be made with respect to the joint materials and geometries
studied.
1. The effects of adhesive nonlinearities greatly influence
the shear stress predictions in the adhesive layer of
bonded joints.
2. The effects of adhesive nonlinearities have little in-
fluence upon the normal stress components in the
adhesive layer of bonded joints.
3. Adherend nonlinear behavior has little effect upon
the adhesive stresses in bonded joints.
4. Residual curing stresses are significant in adhesive
bonded joints. These curing str1~sses are detrimental
in joints with similar adherends, but may be beneficial
in joints with differing adherends.
5. Residual curing stresses are significant in bonded
joints with differin~ adherends ~nd no adhesive.
6. Residual curing stresses are not significantly in-
fluenced by material nonlinearities or temperature
dependent properties.
7. Adherend stiffness has profound 1 ~ffects upon mechani-
cally induced stresses in bonded joints. Stresses
129
130
produced in the adhesive layer of adhesive bonded
joints and along the adherend-adherend interface in
bonded joints without adhesives are higher for
stiffer adherends. In adhesive bonded joints with
differing adherends, maximum adhesi"e stresses
correspond to the more flexible adhi~rend.
8. Adhesive and interfacial stresses a·e non-uniform
with maximum values produced near tie edges of the
overlap region.
9. Adhesive bonded double lap joints are more ef-
ficient single lap joints due to a more uniform
stress distribution in double lap joint.
10. A quasi 3-dimensional analysis predicts a more
flexible joint response than a 2-dimens onal formu-
lation. A larger displacement load is required in
a quasi 3-dimensio1al analysis to predict adhesive
stresses comparable to those of a 2-dimensional
analysis.
11. A quasi 3-dimensional analysis demonstrates the
effects of adherend transverse stiffness and thermal
coefficient of expansion upon the residual curing
stresses.
12. Adhesive stresses are not significantly influenced
by different syrrmetric loadings. Force loadings
produce results similar to displacement loadings.
131
13. The method of solution presented satisfies static
equilibrium very closely.
This analysis has shown that future areas of study might include
the following:
1. Analysis capability for out of plane bending and
warpage.
2. Better representation of stress-strain response
as a function of temperature, and moisture.

ELEMENTAL STIFFNESS MATRIX
Equations (A.l) represent the equilibrium equations for applied
strain loading. Equ's (A.2) represent the equilibrium equations in
average force loadings. In these equations, [K] is the symmetric
elemental stiffness matrix, ~x{S} and {T} are force vectors correspond-
ing to the applied strain and temperature change respectively, {F} is
the vector of applied forces, and {x} is the vector of unknown nodal
displacements.

APPENDlX B ADDENDA TO RFERENCE [l]
During the process of modifying the program developed by Renieri
and Herakovich [l] it was discovered that a coding error had been made
in the equations for the transformation matrices. (Chap. 3, Equ's.
3.9.) This was corrected and the nonlinear stress-strain response pre-
dictions of Ref. [l] were regenerated using the same data and finite
element model. In the majority of cases the differences proved to be
negligible. For the cases where the differences were significant,
comparisons between results obtained from the corrected program and
experiment are presented. It should be noted that the coding errors
applied only to the nonlinear results presentl~d in Ref. [l] and not the
elastic results. It should also be noted tha~ no attempt to define
failure was made by this investigator and that the last point plotted
does not necessarily correspond to failure.

NONLINEAR ANALYSIS OF BONDED JOINTS
WITH THERMAL EFFECTS
by
· Edward A. Humphreys
(ABSTRACT)
A numerical analysis of the nonlinear response of bonded joints is
presented. Mechanical and thermal loadings are considered. Material
stress-strain response is represented by Ramberg-Osgood approximations.
Temperature dependent properties including modulus percent retentions
and coefficients of expansion are modeled with linearly segmented
curves. Bonded joints with graphite-polyimide, boron-epoxy, titanium,
or aluminum adherends are analyzed using a quasi 3-dimensional finite
element analysis. In adhesive bonded joints, the adhesives considered
are Metlbond 1113 and AF-126-2.
Elastic results are presented for single and double lap joints, with
and without adhesives. It is shown that mechanically induced stresses
are greatly affected by longitudinal adherend stiffness. The effects
of adherend transverse stiffness are shown to be significant in some
cases. Residual curing stresses are shown to be significant in all
joints except those with similar adherends and no adhesive.
Norilinear results are presented for adhesive bonded joints. It is
shown that adhesive nonlinearities are only significant in the predicted
adhesive shear stresses. Adherend nonlinearities and temperature de-
pendent properties are shown to have little effect upon the adhesive
stress predictions under mechanical and thermal loadings.
