When we announced the first volume of a Special Issue dedicated to “Crystal Plasticity”, could not expect that great collection 25 excellent articles would be published [...]

The common approach to crystal-plasticity finite element modeling for load-bearing prediction of metallic structures involves the simulation simplified grain morphology and substructure detail. This paper details a methodology predicting structure–property effect as-manufactured microstructure, including true orientation, on cyclic plasticity, fatigue crack initiation in biomedical-grade CoCr a...

This article is concerned with the development of a discrete theory of crystal elasticity and dislocations in crystals. The theory is founded upon suitable adaptations to crystal lattices of elements of algebraic topology and differential calculus such as chain complexes and homology groups, differential forms and operators, and a theory of integration of forms. In particular, we define the lat...

The problem of non-uniqueness in the selection and determination of the amount of shear on the active slip systems has plagued the rate-independent crystal plasticity theories for several years. A new large deformation rate-independent crystal plasticity theory is fromulated which overcomes this long standing problem. The model has been implemented in a commerical finite element program ABAQUS/...

As an extension to strain-gradient models of size-dependent plastic behaviour, this work proposes a model for stress-gradient theory. The is distinguished from earlier works on the topic by its being embedded in thermodynamically consistent framework. development carried out context single-crystal plasticity, and draws conventional plasticity. explored numerically using example torsion thin wir...
