Helpful Hints and Tips: Stress Transformation Formulae for Results Processing
Stress transformation formulae, in terms of the normal (Sx, Sy, Sz) & shear (Txy, Tyz, Txz) stresses, may be either input manually in the Formulae window OR imported as a .PAR file for advanced results processing. The following stress transformation formulae are included in the below download as an importable .PAR file and companion SCW:
- Stress Invariants
- 1st Principal Stress (2D/3D)
- 2nd Principal Stress (2D/3D)
- 3rd Principal Stress (3D)
- von Mises Stress (2D/3D)
- Max Shear Stress (2D/3D)
Note: the error messages may be ignored during .par importation.

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck®. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
