Verification and Validation Technical Brief

Abstract: A fundamental question of computational engineering is whether it is possible to predict the response of some physical system or process to various kinds of excitation by means of numerical simulation with a high degree of reliability. This question is addressed in a document published by ASME. In this note the main considerations are outlined and the relevant capabilities of the finite element analysis software product StressCheck® are summarized.

Testimonials

“We have been having very good success using the P-Version finite element code, StressCheck^®, to develop the 2-D solutions for two independent cracks in a plate. I have asked one of our AFGROW team members to model the plate and lug cases using StressCheck^® and compare them to the existing AFGROW closed-form solutions. [He] modeled the cases several different ways to be sure that he was getting the best possible solutions. He has verified that the bearing load option in StressCheck^® provides excellent results.”
