Coarse-graining of dislocation-mediated plasticity

The regular lattice in which atoms in a metal are arranged can contain line-like defects called dislocations. The dynamics of dislocations is the underlying mechanism for the plastic deformation of metals. Plastic deformation due to dislocation dynamics is currently studied using phenomenological models.  The aim of this work is to derive the material behavior emerging from the collective behavior of dislocations directly from the microscale. To this end, we use methods from equilibrium and non-equilibrium statistical mechanics.
