The unit system for this example problem is shown in the table below.
| Unit System | Metric (mm, kg, N, s, mV, mA) |
| Angle | Radians |
The rubber boot is made of a rubber material that exhibits an elastic response up to the large strain. Therefore, the Neo-Hookean model, an incompressible hyperelastic material model, is used for the rubber material with properties listed in the table and Workbench screenshot below.
| Constants for Neo-Hookean Model | |
|---|---|
| Initial shear modulus (μ) | 1.5 MPa |
| Incompressibility parameter (d) | 0.026 MPa-1 |
