Intro to Modeling Nonlinear Structural Materials with COMSOL®
时长： 18:21
In this 18-minute archived webinar, get an introduction to modeling nonlinear materials for structural analysis in the COMSOL Multiphysics® software. We show how to simulate necking phenomena in an elastoplastic bar and discuss hyperelasticity, viscoplasticity, and other nonlinear behaviors.
