This schema and set of auxiliary files is designed to represent CAMPUS data when used as a complete Databank. M-Base must be contacted to obtain translated input files for the

individual CAMPUS vendors.


Thesaurus (App. 13). This section provides a cross-reference to the attribute names used in each Databank for a given property. It is provided as a tool for searching for information between Databanks.

6TermsThe following is a list of MSC.Mvision and computer terms frequently used in this Reference and when using MSC.Mvision products.

array A matrix of numeric values.attribute Attributes contain the individual data values in the Databank. They are grouped

together into hierarchy relations or property relations.

character A string of characters.Databank Collection of materials information in MSC.Mvision database format. You may use

MSC.Mvision Builder to construct your own materials Databanks. MSC.Software sells or provides free of charge the Databanks described in this publication.

database A generic term referring to a collection of data in an electronic format. MSC.Mvision Databanks are databases created for use by MSC.Mvision software.

footnote A qualification to a specific data entry within a Databank. Footnotes are commonly used to indicate some comment made by the test laboratory about the value. Typical footnotes would add auxiliary information about a numeric data value. For example, you might see a footnote saying, Max. observed value, not ultimate for ultimate strength.

hierarchy The sequence of relations that form the basic structure of a Databank. image A reference to an external image file. metadata A superset of text data which applies to every attribute of a specific type within the

Databank. Metadata is commonly used to identify the test method used to generate the information stored by the specific attribute. Metadata could be an ASTM, ISO, or DIN test number or some type of qualification to the data.

relation All attributes are grouped into relations. There are two types of relations: hierarchy relations and property relations. A property relation sits at the bottom of the Databank hierarchy. Hierarchy relations form the Databank structure. For example, in the PMC90 Databank, the hierarchy relations are Material, Specimen, Environment, and Source.

scalar A single numeric value (integer or real number).


Architecture and SchemaMSC.Mvision uses a certain structure or design for presenting materials information. This architecture is called the Databank Schema and is composed of attributes, relations and a hierarchy of information. The illustration below shows how the three main parts of the Databank schema are associated. The following paragraphs describe these elements in more detail.

Databank HierarchyThe hierarchy defines the basic framework of the Databank. Each level in the hierarchy is composed of a single relation. Each relation is composed of one or more attributes, which are repositories for the materials data. At the bottom of the hierarchy are the properties or data relations. Properties are not included in the hierarchy.

8The Databank hierarchy can be viewed as a vertical line of nodes, where each node is a level in the hierarchy. At the base of the vertical nodes is a spread of nodes, where each node is a table, figure, or image.

There are many approaches to schema design, including attribute naming, in the MSC.Mvision Databanks. This reflects both the historical and evolving concepts in engineering database technology as well as the individual viewpoints of various Databank partners. The following section provides information on currently recommended practices for use with MSC.Mvision software.

Databank AnalogyYou can think of the Databank hierarchy as a series of boxes one within another. The arrangement of these boxes is defined by the Databank schema, with the outside box representing the Databank. When you open the Databank box, you see the first relation in the Databank hierarchy represented by several smaller boxes.

These boxes represent different elements of the top level of the Databank hierarchy. Each box is labeled with the same related types of information. In Databank Structure (Schema) on page 7, the Databank box contains two boxes. One is labeled

7075 Aluminum, and the other is labeled PH15-7 Mo Stainless Steel. The attribute CNAME (Commercial or Common Name) has the value 7075 Aluminum for the aluminum material and PH15-7 Mo Stainless Steel for the steel.

If you open the box with the CNAME of 7075 Aluminum, you will see three smaller boxes. This is the second level of the hierarchy. The boxes within the 7075 Aluminum box are labeled with the attributes TREAT, DIMS and FORM. These are the attributes for the Heat Treatment, Dimension, and Physical Form of the material used during the materials testing. The schema groups these attributes in the relation named SPECIMEN and defines the SPECIMEN relation as the second level in the hierarchy.

The three boxes in the 7075 Aluminum box all have T6 as the value for TREAT. The boxes are labeled differently for both DIMS and FORM. Opening the box labeled T6

10Databank RelationsDatabank relations are composed of attributes and serve several functions within the Databank.

The term relation comes from the fact that relations serve to group information that is related. Relations combine attributes into logical groupings. These groupings are used to organize the data into such elements as tables, curves and images.

Relations are used to form the various levels of the Databank hierarchy. It is the Databank relation that provides the basic structure to MSC.Mvision Databanks.

For example, the TEMP attribute in Databank Structure (Schema) on page 7 is located within the ENVIRONMENT relation. The figure shows a numeric attribute named RATIO. This attribute contains the stress ratio for the fatigue data found at the next level down in the Databank. Stress ratio is in the ENVIRONMENT relation because it is part of the external test parameters that determine the results of the fatigue test.

Understanding the Source RelationThe source relation (see Databank Hierarchy on page 8) is different from the other relations in the Databank. Hierarchy relations form a path for the user to locate needed information. The hierarchy goes from general information to specific. At the bottom of the hierarchy are the property or source relations. These are the table, figure, and image relations. The source relation serves as the link between the hierarchy relations and the property relations.

The source relation serves as a set of super attributes to the property relations. To make tables and figures unique, the system looks in the source relation for the values of these attributes.

Databank AttributesDatabank attributes are the most basic element of the Databank and are found at all levels of the Databank hierarchy. Attributes define the type and format of the data stored within the Databank. Four general categories of attributes are possible: scalar, character, array, and image. See Terms on page 6.

In Databank Structure (Schema) on page 7, the top level of the hierarchy had a single attribute named CNAME. In that example, CNAME is a character attribute standing for Commercial Name.

Attributes also store numbers or number arrays. Again in Databank Structure (Schema) on page 7, the third level of the Databank, ENVIRONMENT, has an attribute named TEMP which stands for Temperature. The value stored in the TEMP attribute is temperature of the material at the time it was tested. Numeric attributes are defined


with specific units and precision. TEMP has units of Fahrenheit and a precision of 1 degree. Curves and images are special numeric arrays that allow for these unique data types.

Every piece of information stored in the Databank is associated with a specific attribute. Attributes are the place holders for materials data. They are used in the query, spreadsheet select, and pick methods of working with MSC.Mvision Databanks.

Attribute NamingThe naming of entities in a database (referred to as attributes here) is a topic of considerable interest and controversy in standards organizations and with most users as well. MSC.Software Corporation is actively involved in a number of standards activities and attempts to follow the developing guidelines wherever possible.

Because of the diversity of opinion in the materials community on this issue, our approach has been to build as much flexibility as possible into the software, so that the user can ultimately have the benefit of the standardized view along with his or her own comfortable view of the data. You are encouraged to participate in standards activities like ISO/STEP or any others that may apply to your technical community. Organizations like NIST and ASTM have been particularly influential in promoting these kinds of standards.

MSC Attribute Naming ConventionsThe attributes at the table and figure (property) level of the hierarchy contain the material properties information that is the heart of a materials Databank. It is important that you give these attributes meaningful names. For this reason, all the Databanks created by MSC.Software Corporation (MSC) use a special attribute naming convention.

The MSC naming convention breaks the attribute name into three parts as follows:

XXXijAA

Property Measured (1-3 letter designation)Direction Measured (1-2 integer designation)Attribute for Direction One (1-2 letters)

12The three parts are Property, Direction, and Attribute. We call this the PDA rule: P for property, D for direction, and A for attribute. For example, YS11T is a common attribute name in the PMC-90 Databank. Breaking this name into its parts results in the following description:

The following is a list of the properties, directions, and attributes commonly used in MSC Databanks:

YS Property measured is Yield Strength.11 Direction is 11 indicating the longitudinal or

principal fiber (warp) direction.T The attribute is tensile.

File Description


To provide examples for building your own schemas and corresponding Databanks.

To create Databanks with identical schema to ones you use regularly and for which you have accumulated similar data sets.

For detailed information on creating your own schema files, consult the Building MSC.Mvision Databanks manual.

Databank Units Conversion FilesThe properties in MSC.Mvision Databanks are stored in a particular system of units. The creator of a Databank selects the default system of units at the time the Databank is initially constructed. MSC.Mvision system uses two external files to control the conversion of numerical values from one system of units to another.

MSC.Mvision searches for a units conversion file at the time a Databank is opened. First, it looks for a units file associated with the Databank in the local directory and then in the Databank directory. The Databank units file is named .unt where is the name of the database without an extension (.des). If a Databank units file is not found then it looks for the file MVISION.UNT again in the local directory and then in the Databank directory. If no units file is found, a message is issued and the Databank is opened without the ability to change units.

The units conversion file uses attribute names to control the conversion process. Curves are a special case for the units file. The units conversion function recognizes curve attributes as two attributes joined by a vs. The units conversion file breaks the curve attribute into its parts and compares the parts to the attribute definitions in the units file.

The units file is a text file using a special syntax to define how to convert database attributes from their default units to another system of units. A sample units file follows:

18DB SI - Customary$CMD m^2/s 0.00064516 EPS micro m/m 1.0E GPa 6.8947572MOLD deg C 0.55555556,-17.777778SIG_RATIO - 1.0SIG MPa 6.8947572YS MPa 6.8947572$DB US - Consistent$YS psi 1.E+3US psi 1.E+3E psi 1.E+6G psi 1.E+6CTE in/in deg F 1.E-6CME in/in %Wt 1.E-6

Sample Units Conversion File


The first entry is the name of the alternate units system. The entry has the following format:

DB Other_name

Where DB marks the line as a new system of units and Other_name is the name of the system of units. In the figure above, there are two systems of units defined, SI -Customary and US - Consistent.

The conversions follow on succeeding lines. The format of the conversion is:

Attribute New_units multiplier [,offset]

Where:

Attribute Name of the target database attribute. Partial names are allowed which provides for simplification of the units file. Partial names are discussed in more detail below.

New_units The name of the new units. Multiplier and offset are numbers used in the following equation to obtain the new value:

New_value = Database_value * multiplier + offset

The conversion line in the sample units file starting with YS means that YS (yield strengths) are to be changed from the default database units of ksi to MPa (MegaPascals) by multiplying the numbers on the database by 6.8947572. This example uses a non-unique name to apply the conversion to all database attributes that begin with YS.

Units Conversion Formatting RulesThe rules for the units file are:

1. The attribute name cannot have embedded blanks.

2. The New_units name must start with an alphabetic character. It can have embedded blanks.

3. Non-unique abbreviated attribute names are allowed. Place abbreviations after longer, more unique names. For example, if using SIG for several different types of stress with the same units and SIG_RATIO for stress ratios, which is unitless, place the longer string first, as above.

4. Abbreviations match attribute names only if the character following the abbreviation is a non-letter. For example, if the abbreviation is E, it would match E_T and E11T but not EPS.

5. The multiplier and offset cannot have embedded blanks.

6. The offset is optional (default = 0.0) and is separated from the multiplier by a comma.

7. Up to five different systems can be defined in a single units conversion file. 8. Comment lines start with a $ in column 1 and can be put anywhere.

209. Results are currently independent of case. A conversion for T meant to apply to T for temperature would also convert attribute t for time better to define attributes uniquely, as TEMP, TIME (or time), etc.

To prevent inadvertent conversions, include unitless items such as SIG_RATIO in the units conversion file. Enter the conversion - for the units and 1.0 for the multiplier. This prevents conversion by the entry for stress terms like SIG.

MSC.Mvision Pro (.map) FilesMSC.Mvision Pro uses several user-definable ASCII text files for the customization and operation of the system. In addition to the units conversion files used by all MSC.Mvision software products, two other files are provided with each Databank specific to the operation of the MSC.Mvision Pro product. They are identified as .map and .mapping.

The mapping file .map is read by MSC.Mvision Pro each time a Databank is loaded and establishes the users working environment for the named Databank. It determines:

Column headers for the Query Results window. Attributes which are searched by the common name query function. Attributes which are displayed in the Pro/E Props window and exported to

Pro/ENGINEER.

You may customize your MSC.Mvision Pro working environment by creating your own .map file. The MSC.Mvision Pro software will search your current and home directories for these files before using the default file located in the Databank installation directories. For detailed instructions for creating your custom file, consult the MSC.Mvision Pro Users Guide.

Export Mapping (.des.mapping) FilesMSC.Mvision Pro, Evaluator, and Builder use the mapping file .mapping to define the material attributes whose values are to be exported from the identified Databank to the preferred analysis program. It relates Databank expressions or queries to the variables defined in the export template. The variables are typically values required by the supported analysis programs. The current release supports the following analysis software:

MSC.Nastran 2001 ABAQUS Version 5 ANSYS Version 4 ANSYS Version 5 COSMOS


Pro ENGINEER

Both the export template and the corresponding mapping file may be customized, and new export templates and mapping files may be created to export to other analysis programs. Please refer to the Users Guide for your software product for detailed instructions.

Additional mappings have been provided for MSC.Fatigue 2003, LS-DYNA, Pamstamp, STAR-CD, nSoft 2001. They are currently uncommented in the mapping file. The corresponding templates will be provided with the next update to the individual MSC.Mvision Materials System products. Further information with be provided with these releases.

Form.definitions FileThe form.definitions file determines viewing options in the software user interface. It may be customized to optimize the viewing interface for your application. By use of a combination of criteria and categories. Categories may be defined by type or property value limitations. For quick property value comparison or cross plotting, you may change the column headers in the Browser. For information on how to edit this ASCII file or create your own forms, consult the MSC.Mvision Users Guide and Reference.

Patran Mapping FilesIncluded with the MSC.Mvision Databanks are all the auxiliary files required to export to MSC.Patran analysis from MSC.Patran Materials. MSC.Patran Materials software uses ..mvtm files to map Databank attribute names to the MSC.Patran material properties needed for analysis. These forms are not ASCII files and, therefore, not editable outside the software. They are created interactively within MSC.Patran. Imbedded within the file name is the MSC.Patran material type. They are defined as follows:

File name P3/PATRAN Material Typeiso Isotropicortho2d Orthotropic in two-dimensionsortho3d Orthotropic in three-dimensionsaniso2d Anistropic in two-dimensionsaniso3d Anistropic in three-dimensions

22Suitability TablesMSC.Mvision software was designed to support engineering requirements for consistent materials information and materials information management within an organization. This compiled data has a wide variety of uses within the CAD/CAE environment. The search, sort, cross-plot, and report functionality of the software makes the data easily usable. Several of the products, specifically, MSC.Mvision and MSC.Mvision Pro assist the engineer in assembling the material property sets from a Databank that will be required for linear, non-linear, temperature-dependent, and strain-dependent materials models for use in analysis. Built-in functions can export data to:

MSC.Nastran Version 2001 ABAQUS Version 5 ANSYS Release 4 and 5 COSMOS

Each of the MSC.Mvision Databanks has been analyzed to determine the number of materials in the Databank that have the minimum data set required to support these materials models for isotropic materials. The minimum data set for each analysis model is listed in the table below:

Analysis Type Minimum Requirements

Linear Youngs Modulus (E), Poissons Ratio (NU), Density (RHO), Tensile Strength (ST)

Structural Youngs Modulus (E), Poissons Ratio (NU), Density (RHO), Tensile Strength (ST), Coefficient of Thermal Expansion (ALPHA), Reference Temperature (TREF)

Non-linear Strain Dependent

Youngs Modulus (E), Poissons Ratio (NU), Density (RHO), Stress vs Strain (SIGVSEPS)

Non-linear Temperature Dependent

Youngs Modulus vs Temp. (EvsTemp), Poissons Ratio vs Temp. (NUvsTemp), Density (RHO), Coefficient of Thermal Expansion vs Temp (ALPHAvsTemp), Reference Temperature (TREF)

Structural Dynamic Youngs Modulus (E), Poissons Ratio (NU), Density (RHO)

Thermal Density (RHO), Heat Capacity (CP), and Youngs Modulus (E)


The Suitability Tables for MSC.Mvision Databanks identify the total number of materials in the Databank, the analysis type, and the number of materials that meet one to all of the properties required. Included in this section is an overview of the types of materials for which all the data sets are met for linear isotropic structural analysis with no dependencies.

31CHAPTER 2sStandards Databank

MIL-HDBK 5 Aerospace Structural Metals DatabankThe MSC.Mvision MIL-HDBK 5 Databank of Metallic Materials is based on MIL-HDBK 5J, the Military Handbook for Metallic Materials and Elements for Aerospace Vehicle Structures. This document is produced under U.S. Air Force contract with the guidance of a volunteer consensus review committee of experts that meets twice yearly, predominantly from the aerospace manufacturers and metal producers industries.

Note: Note that this is a pre-release of this version of the handbook. All data has been approved by the committee. The hardcopy and pdf publications have been compiled, but not released. The pdf files included with this Databank are from the previous release, MIL-HDBK 5J. If the release status is critical to your processes, we suggest that you leave the previous version of this Databank on your computer for reference.

This electronic version of the handbook is maintained for MSC.Software Corporation (MSC) by Battelle Memorial Institute, Columbus, Ohio. The current version represented is MIL-HDBK 5J, dated 1 January 2003, and the MSC revision (mil5.des) is Q2 2005 1.0.

The pdf version of the Military Handbook accessed from within the MSC.Mvision MIL-HDBK 5 Databank provides the textural information that precedes each set of graphs and tables in MIL-HDBK 5J, in addition to a textual copy of Chapters 8, 9, and the Appendices.

Data QualityMIL-HDBK 5 is respected by engineers around the world as one of the most highly evaluated, statistically qualified compilations of design data for metal alloy products available. MSC.Software chose this data source in part to provide a solid baseline for designing materials information software. MSC.Software works closely with Battelle Memorial Institute to ensure the quality of the electronic representation of the handbook.

While the Air Force sponsor and the MIL-5 Coordination Group (of which MSC.Software is a regular member) have been supportive of the computerization of the handbook data, they recognize that they cannot guarantee the accuracy of a commercial product based on the handbook. They have accordingly printed the following statement in the INTRODUCTION of the source document and have asked that MSC.Software (and any vendors of a similar product) reproduce the same in electronic Databanks and documentation:

This printed document, published by the Defense Printing Service Detachment Office, is the only official MIL-HDBK 5. If computerized MIL-HDBK 5 databases are used, caution should be exercised to ensure that the information in these databases is identical to that contained in this Handbook.

32This approach is wise, as every source of technical data, whether printed or electronic, is subject to error, no matter how diligent the publisher may be. Engineers involved in design, analysis, and manufacturing recognize that they must ultimately be responsible for verifying the reasonableness and accuracy of the technical data they use.

Suitability for AnalysisThis Databank includes mechanical and thermal constants, as well as ample temperature and strain-dependent data. It provides a large number of materials that contain all the properties required to create the material models for analysis programs.

Many materials have values for the minimum data set for linear, isotropic structural analysis. These include the following categories of metals in a variety of treatments and forms:

Basic ContentsThe MSC.Mvision MIL-HDBK 5 Databank currently contains all the Design Mechanical and Physical Property tables from the source document, most of the supporting data tables, and almost all the figures that represent the results of numerous different property tests. These include raw or reduced curve data for tests such as tensile and compressive stress-strain (Ramberg-Osgood), fatigue, percent room temperature value versus temperature for various properties, like coefficient of thermal expansion and conductivity and specific heat versus temperature, and others.

The Databank focuses on the design data and background information in Chapters 1-9 of the handbook, which are (as titled in the document):

1) General

2) Steel

3) Aluminum

4) Magnesium Alloys

5) Titanium

6) Heat-Resistant Alloys

7) Miscellaneous Alloys and Hybrid Materials

8) Structural Joints (Fasteners)

9) Guidelines for the Presentation of Data

Low-Alloy Steels Aluminum Alloys

Magnesium Alloys Beryllium Copper

Beryllium Titanium Alloys

Stainless Steels Nickel-Based Alloys


The New MIL-HDBK 5 DatabankMany users of the MSC.Mvision MIL-HDBK 5 Databank are highly familiar with the paper version and prefer to view the Databank in a format which is similar. Consequently, MSC.Mvision has created a version of the MIL-HDBK 5 Databank, .des. In this version, changes have been made to the schema that allow MSC.Mvision to display the data using the chapter layout in the handbook. The install/extract scripts allow you to select this version when installing the MSC.Mvision Databanks.

To create this new version, two more levels were added to the top of the Databank hierarchy. Users who prefer the hierarchy view can pick through the Databank as they would the chapters of the original handbook. The addition of the upper levels also clarifies some of the ambiguity for materials previously identified only by Common Name. The following information discusses the new schema.

Changes to the HierarchyTwo levels were added to the top of the Databank hierarchy. The first level of the hierarchy, having the relation name Category contains the chapter numbers and materials as specified in the chapter headings. These chapter headings are listed in Basic Contents on page 32. The second level of the hierarchy, having the relation name Type, contains the listing of sub-headings for each chapter and an attribute defining the text icon for access to the on-line MIL-HDBK 5 document. For example, selecting Steel from the top level of the hierarchy yields the following selections:

Austenitic Steel Carbon Steel General High Alloy Steel Intermediate Alloy Steel Low Alloy Steel Stainless Steel

Selecting from this screen provides a list of all the alloys of this type for which MIL-HDBK 5 has information, identified by Common Name, Designation, and UNS Number. This is the level at which previous versions of the MSC.Mvision MIL-HDBK 5 Databank started.

34Updating the new MIL-HDBK 5 DatabankMany customers add data to the MSC.Mvision MIL-HDBK 5 Databank. This is typically done using the spreadsheet put command. The addition of the upper levels in the hierarchy does not affect the spreadsheet procedures previously used. The additional data undergoes the same matching process and adds the data accordingly.

If you add to the files by dumping the MSC.Mvision Databank and reloading it with additional input files, the top two levels must be added where appropriate.

1. The top level of the schema is the relation named CATEGORY. It has two attributes named MATERIAL and CHAPTER, corresponding to the chapter headings in the handbook.

2. The second level of the Databank is the relation TYPE. It has two attributes named ALLOY and MIL5_TEXT. This is the name of the group of alloys as designated in the first sub-headings in each chapter.

If you are uncertain of the value to enter for these attributes, query the Databank for the CNAME or DESIG that matches the material being added. Then go to the Criteria Selector and pick Material, and the value will be listed in the pick-list. Repeat the same procedure for Chapter and Alloy. Insert these values into the input file above the relation named MATERIAL.

The following is a sample of an input file for 2014 Aluminum, with the top two levels of the hierarchy added. If the entire input file contains only one type of alloy, these two levels need only be added once at the beginning of the input file. Otherwise, it must be added each time the alloy changes in the input file.

These two levels were added to the input file containing data for 2014 Aluminum Alloy


Form.definitions Files for MIL-HDBK 5 DatabankThe MIL-HDBK 5 Databank is provided with three forms, providing versatility in viewing the Databank. The Criteria Panel is the same for all three. The primary differences are in the list of Material Sets.

The form labeled METALS ----Metals Data from Military Handbook 5 (LONG FORM) contains a list of all the relations in the Databank. The view of data in the Materials Browser is limited to the materials for which the selected relation exists.

The form labeled METALS ----Metals Data from Military Handbook 5 (SHORT FORM) contains an abbreviated list of the same relations in the Materials Set, including only the most commonly used relations.

The form labeled METALS----Metals Data from Military Handbook 5 (INDEX) presents the Materials Set in a layout similar to the index of the original paper handbook. Selecting a category of materials from the Index form limits the materials in the Materials Browser to those included in the corresponding chapter of the handbook.

MIL-HDBK 5 form duplicates the index of the original handbook.

Pick a chapter or section of that chapter.

36Displaying Handbook Figures and TablesWhen using any of the forms for MIL-HDBK 5 Databank, it is easy to view a particular table or figure by its number in the handbook. Simply select the button labeled Source figure number... or Source table number... in the Criteria Panel.

Selecting a figure number reduces the Materials List to include the one material displayed in that figure in the handbook. Select Display at the bottom of the Materials List to view the figure.

To view a property table as it is displayed in the handbook, use the following steps:

1. Select a table number to reduce the Materials List to all the materials for which data is displayed in that table in the handbook.

2. Pick Select All from the Function Menu or from the pop-up menu accessed using the right mouse button when the cursor is in the Materials List.

3. Select Display.

The information at the top of the tables in the handbook is found in the Pedigree window to the right of the tabular display in the Data Viewer.

Note: This technique for viewing tables requires that List All Materials be selected in any of the three forms, that Materials w/ Property Data be selected in the Long or Short forms, or that any chapter be selected from the Index form.

Displaying Handbook TextBattelle Memorial Institute has translated MIL-HDBK 5 to a .pdf formatted file that is made available on CD-ROM by the U.S. Air Force.

MIL-HDBK 17-1A Reinforced Plastics DatabankThe MSC.Mvision MIL-HDBK 17A Databank of Structural Composite Materials is based on MIL-HDBK 17A, Military Handbook of Plastics for Aerospace Vehicles, Part I-Reinforced Plastics. This document was produced by the Air Force Materials Laboratory for the Department of Defense and the Federal Aviation Administration. The source document has recently been revised and included as an appendix in the new MIL-HDBK 17F for Polymer Matrix Composites, a military handbook for which an electronic Databank product is currently under development.

The MIL-HDBK 17A electronic Databank is maintained by MSC.Software Corporation (MSC). The source document represented is through Change Notice 1, dated 1 September 1973. The MSC Databank (mil17a.des) revision is Q4 1995 2.0.

Suitability for AnalysisThis Databank contains mechanical and thermal constants as well as temperature-dependent and strain-dependent data. However, none of the materials in this Databank include all the properties required to create the material models for the specified analysis programs. Generally, the attribute which has no value is Poissons Ratio. You will need to supplement the data from other sources.

Basic ContentsThe MIL-HDBK 17A Databank currently contains most of the data from the Mechanical Properties tables and all the figures representing the results of the various property tests in Chapter 4 of the handbook.

The following structural composite material types are represented:

Fiberglass/Epoxy Laminates Fiberglass/Phenolic Laminates Fiberglass/Silicone Laminates Fiberglass/Polyester Laminates Boron/Epoxy Laminates

Note: Some of the material products described in this handbook are no longer produced. Even in those cases, the data can be useful when searching for typical properties for a certain type of composite or for historical purposes, such as studying the aging characteristics of structures built at some earlier date.

50Default Units and Units ConversionThe default units are US Customary and follow the handbook in almost all cases where it is consistent. For all strain parameters, micro-in/in is used throughout (instead of % or in/in or mil/in).

54MIL-HDBK 17-2F Polymer Matrix Composites DatabankThe MSC.Mvision MIL-HDBK 17F Databank of Polymer Matrix Composite Materials contains updated data to MIL-HDBK 17-2F, Polymer Matrix Composites, Volume 2, Material Properties.

This handbook was developed under sponsorship of the Department of Defense and the Federal Aviation Administration with Army Research Laboratory standardization responsibility. The handbook is written by a consensus review coordination group with participants representing the DOD, NASA, FAA, industry, and academia, both national and international. The review process for the data in Volume 2 consists of a statistical and technical review by the MIL-HDBK 17 Secretariat, Materials Sciences Corporation. The results are subject to approval by the Data Review working group, the MIL-HDBK 17 Coordination group, and a DOD coordination review.

The handbook printed by the government is the only official version of MIL-HDBK 17. It is available from the Department of Defense Single Stock Point, Building 4D, 700 Robbins Avenue, Philadelphia, PA 19111-5094. This electronic Databank is based on the handbook and is maintained for MSC.Software Corporation by Materials Sciences Corporation, Fort Washington, Pennsylvania.

The current handbook version that forms the basis of the Databank is MIL-HDBK 17-2F, dated 17 June 2002 and the MSC revision is Q3 2002 1.0.

Data QualityMIL-HDBK 17F data is divided into three classes based on requirements for sampling, data documentation, and test methods. These requirements are described in MIL-HDBK 17-1F, Polymer Matrix Composites, Volume 1, Guidelines.

Screening DataLimited data obtained for the purpose of screening materials for future use. Handbook screening mechanical property data often comes from a single material batch, with typically a minimum of five specimens. In addition, data from test methods which do not meet handbook criteria are identified as screening data. An example is the short beam shear test for which all handbook data is limited to the screening class.

Interim DataData that represent a larger population than screening data but do not meet the specific sampling or data documentation requirements required for fully approved data. MIL-HDBK 17F interim mechanical property data must come from at least 3 batches totaling at least 15 coupons.


Fully Approved Data (with B-Basis Values)Statistically-based material properties that represent a minimum of five batches with at least thirty specimens and meet data documentation and test method requirements in MIL-HDBK 17F, Volume 1. These data documentation and test method requirements are more stringent than those for screening an interim data.

Suitability for AnalysisThis Databank contains mechanical as well as temperature-dependent and strain-dependent data. However, few of the materials in this Databank include all the properties required for the material models for the specified analysis programs. You will need to supplement the data from other sources. This database contains no thermal data as of this release.

The Databank contains following materials which meet the minimum data set to support the materials models used in linear, isotropic structural analysis:

Carbon/BMI Carbon/Epoxy Carbon/PEEK

Basic ContentsThe MIL-HDBK 17F Databank currently contains all of the data from the Mechanical Properties tables in Chapters 4 and 10 of the handbook. The following polymer matrix composite material types are represented:

Default Units and Units ConversionThe default units are US Customary with the exception of all mass densities (g/cm3) and fiber areal weight (g/m2) and follow the handbook in all cases. For all strain parameters, microstrain is used throughout (instead of % or in/in).

Carbon/Epoxy Carbon/Bismaleimide
