TL;DR: In this article, the spectral crystal plasticity (SCP) model has been extended to simulate non-monotonic deformation processes with heterogeneous boundary conditions, and a new model that enables simulations of complex, nonlinear deformation process with heterogenous boundary conditions is presented.

TL;DR: In this paper, the authors provide a novel method enabling the use of realistic material strain rate-sensitivity exponents to be used within the crystal visco-plasticity theory without increasing computation time involved in polycrystal simulations.

TL;DR: In this article, the authors present a computationally efficient, multi-scale model based on crystal plasticity theory for simulations of heterogeneous plastic deformation of metallic components in commercial finite element (FE) codes.

TL;DR: In this article, the authors study the mechanical response and texture evolution of alpha-uranium during simple compression and rolling at 573 K. In order to determine the underlying mechanisms governing plasticity and texture formation, they perform detailed characterizations using electron backscattered diffraction and constitutive modeling using a dislocation-density based hardening law within a visco-plastic self-consistent homogenization.

TL;DR: In this paper, the authors present estimations of average intragranular fluctuations of lattice rotation rates in polycrystalline materials, obtained by means of the viscoplastic self-consistent (VPSC) model.
