How to Evaluate Stress and Yielding in Plasticity — Lesson 2

An object that develops plasticity, upon unloading, will have permanent deformation. It seems easy to evaluate yielding, as it can be determined by checking the von-Mises stress against the yield stress, or by checking whether the equivalent plastic strain value is above zero. But we need to know some key concepts for accurate assessment; ignoring them may lead to inaccurate interpretations. In this video, we will focus on how to evaluate and interpret plasticity results.
