Helpful Hints and Tips: Applicability of Global-Local Methods
Abstract: Applicability of Global-Local methods such as TLAP-Traction is described. Global-Local methods may not be applicable if Saint-Venant’s principle is violated.

“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.”
