Tips & Tricks for Modeling Plasticity - ANSYS e-Learning

Linear elastic material modeling is an excellent assumption for structures that undergo small deformations and return to their original shape upon removal of load.  Using just an elastic modulus and Poisson's ratio for the initial simulation is a good practice for all analyses, since it solves in a single iteration and provides benchmark stress results.  However, many materials undergo permanent deformation and/or soften with increased loading making this linear assumption invalid. More accurate simulations require a nonlinear material model. Plasticity is the most common material law incorporated into FEA simulations.

CAE Associates’ Vice President Peter Barrett guides you through key tips and tricks for modeling plasticity using ANSYS Workbench.  Learn how to:

  • Identify analyses where the simulation of plasticity is important
  • Understand the dos and don’ts of defining both kinematic and isotropic hardening material properties
  • Gain insight into obtaining nonlinear convergence with plasticity
  • Effectively post-process analyses that include plasticity

If you are running linear material models in Workbench Mechanical and want to learn some new tips for incorporating plasticity into your analyses, view this e-Learning session to expand your analysis expertise.
