Micro Abstract:
The eigenfracture scheme is a suitable technique to model brittle fracture. This method faces challenges when dealing with inelasticity. The contribution at hand is focused on an eigenerosion formulation for Drucker-Prager plasticity. Its binary approach, leading to element stiffness degradation, can be implemented in a straightforward manner into a finite element code. Special attention is paid to the distinction of tension and compression. The method is validated by a numerical example.
