CES 512- Computational Analysis Methods for EngineersMini Project:inite Element Method !EM"

Project outcome:At the end of this mini project, student should be able to:Solve the truss problem with Finite Element method by hand and software

approach (C1!"#, C$!"%&'

he element of comple) en*ineerin* in this project is shown by directin*student to thin+ an approach desi*nin* the structural element to meets theprescribed displacement values'

#nstruction:

i& Analye the problem with any -nite element (FE& software (e'*' ./SAS,0isualFEA'&'Analye the problem usin* manual structural analysis with the

help of pro*rammin* software (A.A2, E3CE., F44A5, etc'&' Compare,discuss and present the results of both calculations'ii& 6esi*n the structure accordin* to the re7uired speci-cation'iii)Submission date: Week no. 14 (actual date to confrm with the

respective lecturer)

as+s:

he *iven problem consists of truss which is pin supported at A and rollers at 2'he problem information is shown in the Fi*ure 1'

1' 2y usin* the Finite Element ethod, compute manually

a& he nodal displacements, reactions forces, and element stresses of thetruss

(C1!"$& ! C#:18918918;8m

b& 6etermine the ma)imum nodal displacement of the truss and its location'Evaluate with justi-cation why the ma)imum displacement occur at thatparticular location'

(C1!"$& < C#:#m (C$!"#& ! C=: %m

c& Compare and verify your answers on section a& and b& usin* the FiniteElement software'

(C$!"#& ! C=: ;8m

$' 6esi*n the structure such that the ma)imum nodal displacement does note)ceed 18mm, but at least *reater than > mm' E)plain your approach on theprovidin* solution and verify your approach usin* the -nite element

software' ?*nore the wei*ht of the section used for the calculation' (C$!"%&! C= : 18918m918m
