Hyperelastic Materials in Material Library
You can choose a material model for the hyperelastic material using experimental data for stress and strain. You must select the Define By Tests check box on the Material Definition dialog box and specify the experimental data in the Hyperelastic Material Definition dialog box.
When you use the Define By Tests option to create a new material and click Save To Library to save the material to the material library Creo Simulate uses the following guidelines:
• Stores only the coefficients for the material model.
• Does not save the test data used to choose the material model and displays a warning message.
• Clears the Define By Tests check box.
Similarly, when you are editing a material from the material library, you can not select the Define By Tests check box on the Material Definition dialog box. You can select a material model and specify the values of coefficients for a material model on the Material Definition dialog box.
