Micro Abstract:
Considering a geometrically exact description, only isotropic classical cohesive zone models fulfill fundamental principles such as material frame indifference and thermodynamical consistency. The ability to model shear and anisotropy is limited. Within this talk, a novel interface model, which is consistent with the above mentioned fundamental principles, is presented. Besides the simulation of anisotropic hyperelasticity, numerical results for anisotropic material degradation are shown.
