Plastic Hardening Law Definition Dialog Box
Use the Plastic Hardening Law Definition dialog box to:
Specify experimental data for true stress versus true total strain.
 
* You need to specify only the data at the yield point and for the plastic part of the stress-strain curve.
Plot a graph of the true stress versus true total strain values.
Select a hardening law and specify best-fit material coefficients or allow Creo Simulate to automatically select the hardening law and calculate material coefficients.
Draw the best-fit curves for different hardening laws.
The Plastic Hardening Law Definition dialog box consists of the following areas:
Test Area—Creates tests to specify the true stress and true total strain values in a table.
Graph Area—Plots the true stress and true total strain values specified in a test and draws the best-fit curves for different hardening laws. Use these curves to choose the material model for the creation of elastoplastic materials.
Material Model—Finds the best hardening law for the test data. You can choose the hardening law material model to draw the best-fit curve and read the root mean square (RMS) error for the material model.
Menu and Toolbar Buttons—Quick access to various actions.
