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.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck®, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck® as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
