Method of AnalysisStructures were originally drawn in ProE

and saved as .IGES files. Structures were

then imported into ANSYS Workbench foranalysis.

Once geometry was imported, fixedsupports and loading conditions were

added.Structural Analysis was completed.Von-Mises stresses.

Total Deformation.

Theoretical BackgroundVon Mises Stress1

The Von Mises criteria is a formula for combiningthese 3 stresses into an equivalent stress, whichis then compared to the yield stress of thematerial.

If the Von Mises Stress exceeds the yield stressdivided by a safety factor, then the material is

considered to be at the failure condition.

ConclusionsBenefits of angular supports:

Equivalent Stress Area exhibiting maximum stress was reduced.

Maximum stress reduced by approximately 35 psi.

Total Deformation Area exhibiting maximum deformation was reduced.

Detriments of angular supportsSlightly more deformation across total area of

the platform.
