Micro Abstract:
The implementation of geometrically nonlinear crystal plasticity into a hybrid discontinuous Galerkin (DG) framework is presented using a regularization technique for very high strain rate sensitivity exponents. This combination leads to a numerically efficient and locking-free model. The performance of the regularized hybrid DG crystal plasticity is examined on a planar single crystal.
