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.

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck® (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
