Abstract
A 2D FEM approach for studying dislocation-phase boundary interaction is proposed. By adopting the classical Peierls-Nabarro model as a glide plane model, a natural interplay between dislocations, external boundaries and phase boundary is provided. Thereby the local dislocation induced stress field in the vicinity of the phase boundary can be fully captured. Modelling dislocation dipoles (loops) in a finite-sized grain introduces a grain-size dependency. With this model the effect of dislocations piling up against a phase boundary and
dislocation transmission are studied for a glide plane perpendicular to a fully coherent and non-damaging interface.
