PRINSTR STRESS PROCESSOR

This program is a simple Windows pop-up which uses classical methods to solve the cubic equation required to find principal stresses from the six stress components. This is an exact solution, not an iterative process. Six stress components are entered by the user, and the resulting principal stresses are calculated, as well as stress intensity and von Mises equivalent stress.

THERMAL STRESS PROGRAM

The THERMAL program uses classical methods to calculate thermal stresses in a cylindrical vessel. The internal and external surface temperatures, internal pressure, and axial load are input into the program, and the results include principal stresses at the inside and outside surfaces, as well as total stress intensity values to compare to code allowables.
