Hi Hywel,
I have a couple of questions regarding your model:
- How did you obtain the strain-at-break value for this material? Was it determined experimentally in a standard uniaxial tensile test under quasi-static conditions?
- I can see that you employed the Multilinear Isotropic Hardening model to describe the plastic response. By doing so, do you simplify the behavior of your “composite” material to behave like a homogeneous material?
