I am currently modelling the transverse compression of a gold fibre using FEA software, and I was wondering what plasticity model would be good. I'm thinking of using Johnson-Cook's plasticity model, but I then have no idea where to get the necessary parameters. If there is no good model, where can I obtain the values for stress-strain curves?
Sorry if my post is vague, I'm extremely new in this field and could use some enlightening.
