Chapter 31: Fitting Parameters for a Chaboche Kinematic Hardening Model

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:

You can also perform this example analysis entirely in the Ansys Mechanical Application. For more information, see Fitting Parameters for a Chaboche Kinematic Hardening Model in the Mechanical Technology Showcase: Example Problems.
