| Constitutive Model | Microplane damage model (anisotropic damage model) |
| Constitutive Properties | E 30.e3 n 0.18 ep 8.6666666667e-05 Gf 0.010 md 0.05 nmp 10 R 5.0 nonloc 1 |
| Number of microplanes | 10 |
| Error Estimator&Indicator | ZZ-error estimator for elastic regions (15%), Damage level as indicator for inelastic areas |
| Remeshing criteria | Default mesh size (100) for regions with no damage. Inside damaged regions linear interpolation of mesh density, here taken as constant (4) for damage indicator > 0.1. |
| Mesh Generator | t3D (author Daniel Rypl) |
