This tool performs several transformations and compares multiple failure theories for a given stress tensor.
- Calculates the principal stresses and stress invariants
- Calculates Max Shear stress per Tresca failure theory
- Calculates von Mises stress and compares two methods of determining sign for use with Signed von Mises criterion
- Plots Mohr's Circle for 2D or 3D stress states
- Principal stresses and invariants: Cauchy Stress Tensor (Wikipedia)
- Max Shear failure theory: Tresca yield surface (Wikipedia)
- vonMises Yield criterion (Wikipedia)
- Signed von Mises (invariant method): Fatigue Toolbox, s3.1
- Signed von Mises (Principal stress method): ref TBD
- Mohr's Circle (Wikipedia)
