Among the severe plastic deformation processing (SPD) of materials, high-pressure torsion
(HPT) is known to induce considerable amounts of plastic strain and crucial grain refinement …

Severe plastic deformation (SPD) has established itself as a potent means of producing bulk
ultrafine grained and nanostructured materials. It has given rise to burgeoning research that …

An accurate homogenization method that accounts for large deformations and viscoelastic
material behavior on microscopic and macroscopic levels is presented. This method is …

A large number of polycrystalline materials, both manmade and natural, display preferred
orientation of crystallites. Such alignment has a profound effect on anisotropy of physical …

Various self-consistent polycrystal plasticity models for hexagonal close packed (HCP)
polycrystals are evaluated by studying the deformation behavior of magnesium alloy AZ31B …

We present a detailed description of the numerical implementation, within the widely used
viscoplastic self-consistent (VPSC) code, of a rigorous second-order (SO) homogenization …

A new model is proposed that aims to capture within a single modelling frame all the main
microstructural features of a severe plastic deformation process. These are: evolution of the …

A recent strain hardening model for late deformation stages (Estrin, Y., To´ th, LS, Molinari,
A., and Bre´ chet, Y., Acta Materialia, 1998,“A dislocation-based model for all hardening …

Crystal plasticity models evolve a polycrystalline yield surface using meso-scale
descriptions of deformation mechanisms. The activation of deformation mechanisms is …

The formulations of self-consistent schemes for elastic-plastic deformations of polycrystals
are based on the solution of an ellipsoidal inclusion embedded in an infinite matrix. Because …
