# Workpiece Material Models

Inside the user profile, materials are assigned for the workpiece (billet) and the boundary faces of the workpiece components. HX-Forge supports the following three constitutive models for metals:

1. | Inverse Sine Hyperbolic model |

2. | Metal Forming Power Law model |

3. | Norton-Hoff model |

The following table contains descriptions of data types for Workpiece material properties:
