  Hello Everyone,
  I was trying to model cyclic plasticity using chaboche Kinematic hardening model. I noticed that when you input a chaboche Kinematic hardening model a curve fitting option becomes available. When you include the curve fitting option a uniaxial plastic strain test data input area where it says add experimental data becomes available. Can anyone please explain to me how I can input the uniaxial plastic strain test data and how I can get the chaboche parameters?
  Thanks.
