Owing to its ability to incorporate Schmid's law at each integration point, crystal plasticity has
proven a powerful tool to simulate and predict the slip behavior at the grain level and the …

There exist two frameworks of strain gradient plasticity theories to model size effects
observed at the micron and sub-micron scales in experiments. The first framework involves …

Gradient nano-grained (GNG) materials, inside which grain size increases gradually from
nano-scale in the surface to micro-scale in the substrate, have shown synergetic strength …

Hexagonal materials deform plastically by activating diverse slip and twinning modes. The
activation of such modes depends on their relative critical stresses, and the orientation of the …

In this work, we develop a modeling framework for predicting the visco-plastic deformation,
microstructural evolution (distributions of grain shape and size) and texture evolution in …

In this paper, modifications are proposed to a phenomenological plasticity model to account
for the evolution of recrystallization and the resultant softening behavior. The novel model …

The indentation size effect in spherical indentation experiments is studied via the
conventional theory of mechanism-based strain gradient plasticity (CMSG) established from …

A multiscale approach including a finite element framework for polycrystal plasticity is used
to model jerky flow, also known as the Portevin–Le Chatelier effect. The local constitutive …

Nix and Gao established an important relation between microindentation hardnessand
indentation depth. Such a relation has been verified by many microindentation experiments …

When copper is deformed to large strains its texture and microstructure change drastically,
leading to plastic anisotropy and extended transients when it is reloaded along a different …
