I have been modelling a Nitinol part using the Nitinol
material model. However, my experimental stress strain data shows
that the material is not perfectly linear during the initial part
of its curve. The Nitinol model does not seem to allow for this. In
the past, this material would have been modeled using a non-linear
Is there any other benefit to using the Nitinol model over a
Non-linear model in this case? or is there any way to model this
type of behavior in the Nitinol model?
