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.
| Constants for Neo-Hookean Model | |
|---|---|
| Initial shear modulus (μ) | 1.5 MPa |
| Incompressibility parameter (d) | 0.026 MPa-1 |
In addition, the coefficient of friction for the rubber material is set to 0.2.
