Dislocation Motion Induced by Thermally Driven Phase Transformations

Dislocation Motion Induced by Thermally Driven Phase Transformations The interaction of dislocations with phase boundaries is an interesting aspect of the interplay between phase transformation and plasticity at the nano‐scale. We capture this interaction within a phase field framework coupled to discrete dislocation dynamics. In order to regularize the stress and driving force for phase evolution at the dislocation core, a first strain‐gradient elasticity approach is used, which leads to more physical, discretization‐independent numerical solutions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings in Applied Mathematics and Mechanics Wiley

Abstract

The interaction of dislocations with phase boundaries is an interesting aspect of the interplay between phase transformation and plasticity at the nano‐scale. We capture this interaction within a phase field framework coupled to discrete dislocation dynamics. In order to regularize the stress and driving force for phase evolution at the dislocation core, a first strain‐gradient elasticity approach is used, which leads to more physical, discretization‐independent numerical solutions.
