Defining a Multilinear Plasticity Hardening Model Using Ansys Mechanical — Lesson 1

Most metals undergo plastic deformation when subjected to loads beyond their elastic limit. During this deformation, they lose overall stiffness but undergo strain hardening, which increases their yield strength. In applications viz, metal forming and forging, it is important to include this behavior to accurately capture the mechanics. In Ansys Mechanical, this behavior is captured using several plasticity models, and multilinear hardening is one of the most used. It is easy to set it up, but one must understand how to extract the model parameters from experimental data. In this video, we will learn to define this material model from experimental data. For demonstration purposes, we used the data for the 316L stainless steel material published in this peer-reviewed article: https://doi.org/10.1016/j.ijpvp.2008....
