This example problem demonstrates how to determine material parameters for a third-order Chaboche kinematic hardening model using the curve-fitting tool.
A method is presented to estimate the initial parameters and obtain a least-squares best fit to the data. The fitted parameters are validated by conducting uniaxial simulations using a single element and comparing the results with the experimental data.
The following features and capabilities are highlighted:
