Nonlinear elastic material model

August 12, 2018 by Cyprien Leave a Comment

Some materials (especially plastics) tend to have an elastic region which is nonlinear in itself.

It means that if you applied a load with a value inferior to the yield stress and then you unload your model, the model will effectively come back to its original shape… but the stress and strain won’t follow a linear relation of proportionality.
