Strain gradients have been cast in the form of geometrically-necessary dislocations (GND) to
relate the length-scale dependence of strength and to determine potential sites for failure …

A gradient-enhanced crystal plasticity model is presented that explicitly accounts for the
evolution of the densities of geometrically necessary dislocations (GNDs) on individual slip …

This paper focuses on the continuum scale modeling of dislocation–grain boundary
interactions and enriches a particular strain gradient crystal plasticity formulation (convex …

A gradient crystal plasticity theory is presented including a defect energy based on the
gradient of an equivalent plastic strain measure. Preserving the single crystal slip …

Hardening relations describe the increase in resistance to deformation during plastic flow.
Three hardening relations are compared here in the context of conventional large-strain …

The present work investigates a new approach to formulating a rate-independent strain
gradient theory for crystal plasticity. The approach takes as offset recent discussions …

The geometrically non-linear scale dependent response of polycrystal FCC metals is
modelled by an enhanced crystal plasticity framework based on the evolution of several …

As the characteristic scale of products and production processes decreases, the plasticity
phenomena observed start to deviate from those evidenced at the macroscale. The current …

We present a finite element method for the analysis of ductile crystals whose energy
depends on the density of geometrically necessary dislocations (GNDs). We specifically …

The implementation of novel material models in the microscale gives a deeper
understanding of inner and intercrystalline effects of crystalline materials. For future works …
