Polynomial Hyperelastic Model

Application ID: 12051

This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney-Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined expression: a two-term equation and a five-term equation. The two-term Mooney-Rivlin material model implementation is then validated with the results obtained with the predefined Mooney-Rivlin hyperelastic material.
