| Abstract: |
| This presentation deals with techniques for the spatial and temporal discretization
of models for rate-independent damage featuring a gradient regularization.
Different methods in dependence of the choice of the gradient term
and related convergence results are discussed.
The ideas are also demonstrated for a phase-field fracture model at finite strains,
which takes into account the anisotropy of damage by applying an anisotropic split
and the modified invariants of the right Cauchy-Green strain tensor.
Numerical examples in two and three space dimensions are presented. |
