Curve Fitting Chaboche Kinematic Hardening Parameter Using Uniaxial Plastic Strain Data

      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.

      nOpen the ANSYS Help. Go to Mechanical APDL. Go to Material Reference. Read Chapter 6.3n
