I have successfully run the simulation several times on various surfaces. I have used Johnson-Cook parameters and specified material properties. However, I am not sure if Ansys automatically accounts for kinematic strengthening and other stress/strain effects on the materials. Any insights would be appreciated as to how much information I am required to input to maximise accuracy of the damage and plasticity models.n(Note: I do not have any self-conducted experimental data to make a comparison to).nThank you.n
