I'm trying to build a model in Abaqus to simulate a three-point bending test. My goal is to compare a simulated force-displacement curve with experimental data in order to retrieve some key properties (e.g., Young's modulus, Yield Stress and Ultimate Stress) of novel aluminum alloys.

It is reasonable to model the plasticity of this material in this case by using the Ramberg-Osgood law? If so, is there any way to also incorporate the Poisson's Ratio?
