Multilinear hardening elasto-plastic material model

August 12, 2018 by Cyprien Leave a Comment

This model is an improvement of the previous model. Instead of considering the stress constant equal to the yield stress in the plastic region,  plastic stresses are calculated using a “hardening” curve.

nonlinear material model

It is called “multi-linear” because the hardening part (the nonlinear part of the curve) is calculated using a series of points provided by the user (you) and then approximated with a linear approximation on each segment between the points.
