Modelling nonlinear elastoplasticity of a material using Comsol Multiphysics- Structural mechanics

This tutorial shows a simple example of how non-linear plastic deformation can be modelled using the solid mechanics physics interface. The applied force is gradually increased to a maximum and then reduced to zero. The resulting stress-strain curve is hysteretic due to permanent plastic deformation. The slope of the stress-strain curve when unloading is equal to the slope of the curve in the initial elastic region. 00:00 Introduction 00:38 geometry 01:04 Material selection 02:25 Physics 03:34 Plasticity model 08:03 mesh 08:17 Solver settings 09:44 Results 11:02 Stress-strain curve Please subscribe and feel free to ask questions in the comments.
