Modeling dislocation multiplication due to interaction and reactions on a mesoscopic scale
is an important task for the physically meaningful description of stage II hardening in face …

A set of evolution equations for dislocation density is developed incorporating the combined
evolution of statistically stored and geometrically necessary densities. The statistical density …

Dislocations are the most important material defects in crystal plasticity, and although
dislocation mechanics has long been understood as the underlying physical basis for …

In the last decades, the numerical prediction of the deformation behavior of materials has
become more and more important. On the one hand, there is an ever growing demand for …

We present a crystal plasticity model that incorporates cross-slip of screw dislocations
explicitly based on dislocation densities. The residence plane of screw dislocations is …

The plastic deformation of metals is the result of the motion and interaction of dislocations,
line defects of the crystalline structure. Continuum models of plasticity, however, remain …

Dislocation junctions are considered to control the hardening behavior of crystalline
materials during plastic deformation. Here the influence of the glissile junction on the plastic …

A small-strain two-dimensional discrete dislocation plasticity (DDP) framework is developed
wherein dislocation motion is caused by climb-assisted glide. The climb motion of the …
