A new simulation example entitled, “Hyperelastic-Viscoelastic Material Calibration of Butyl Rubber,” is available in the R2022x FD01 user assistance. It is the second example that illustrates the capabilities of the Material Calibration app. All of the information in the example is presented with clear, step-by-step instructions that should take you about 30 minutes to complete.

The example’s workflow begins with you importing multiple sets of stress-strain test data from test at different strain rates. You then select an appropriate material model to calibrate to your test data, adjust the initial material parameters, apply more weight to selected test data sets, and select an optimization algorithm. After you successfully calibrate the model, you export it as a new material definition in the 3DEXPERIENCE database. You can apply the new material definition to a product assembly for a future simulation, ensuring that the material’s response replicates real-world behaviors.

To learn more and complete the example for yourself, see Hyperelastic-Viscoelastic Material Calibration of Butyl Rubber.

The SIMULIA Simulation Examples team is soliciting ideas for new examples.
