Von Mises yield and Von Mises ultimate failure analyses (2D and 3D)

Von Mises yield failure theory uses the yield strength of the isotropic material, SY.

Von Mises ultimate failure theory uses the ultimate tensile strength of the isotropic material, SU.

Strength Ratio

This software computes the strength ratio, SR, as follows:

For the Von Mises yield theory:

For the Von Mises ultimate theory:

where σVM is the Von Mises stress computed as follows:

• For a 2D isotropic material:

• For a 3D isotropic material:

Failure Index

This software computes the failure index, F, as follows:

Margin of Safety

This software computes the margin of safety, MS, as follows:
