Constitutive Law
This MPM material is an anisotropic hyperelastic material for dry woven fabrics in forming simulations. This material is only suitable for membrane particles defining a 2D fabric plane in 3D simulations.
Material Properties
These properties can be determined by various fabric tests.
| Property | Description | Units | Default |
|---|---|---|---|
| THETA0 | 0 | ||
| Eyarn | Equivalent elastic modulus of the fabric | pressure units | 0 |
| nu | Equivalent elastic modulus of the fabric | none | 0 |
| T10 T11 T12 T13 T14 |
Traction interpolation coefficient in direction 1 | pressure units | 0 |
| T20 T21 T22 T23 T24 |
Traction interpolation coefficient in direction 2 | pressure units | 0 |
| SH0 SH1 SH2 SH3 SH4 SH5 SH6 SH7 SH8 SH9 SH10 SH11 SH12 |
Shearing Interpolation coefficient in the 1-2 plane | pressure units | 0 |
History Variables
This material uses four history variable:
- J or the determinant of the deformation and equal to V/V0.
- Theta 0 history
- l1 history
- l2 history
