StressCheck Tutorial: Checking ITP Viability for Solving Nonlinear Events
Abstract: Case study for the checklist to determine the viability of performing Incremental theory of plasticity (ITP). Overload, unload, re-load and unload events studied for a U-shaped member under “pull apart” loads. Results between Deformation theory of plasticity (DPT), General nonlinear (geometric nonlinear + DPT) and IPT solutions for the initial overload event are compared.

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
