Using Simulation, I am working on a nonlinear nitinol material model. I was under the impression that nitinol can have different Young's modulus associated with either the austenite or martensite formation of the material. However, SolidWorks Simulation only appears to have one input for the Elastic Modulus in the material properties. Does anyone know of a way to adjust the stress-strain profile so that there are different Young's modulus depending on whether the part is loading or unloading?
