Geometrically nonlinear crystal plasticity implemented into a discontinuous Galerkin element formulation

Single crystal viscoplasticity, with a regularization technique for the power law, is presented and implemented into a discontinuous Galerkin (DG) framework. Although single crystal plasticity has been extensively studied, its examination with the regularization method in combination with a DG formulation leads to a numerically efficient and robust model. The performance of the DG framework in crystal viscoplasticity is shown by an example. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
