Numerical Modelling of the Effects of High Strain Rate, Strain Path and Particles on the Formability of FCC Polycrystals
A new crystal plasticity scheme for explicit time integration codes is developed based on a forward Euler algorithm in the first part of this paper. The new numerical model is incorporated in the UMAT subroutine for implementing rate dependent crystal plasticity model in LS-DYNA/Explicit. The materi...
