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.From a
mathematical point of view, this results in a system of
coupled partial differential equations (PDEs) and ordinary
differential equations (ODEs). The PDEs include an equation
analogous to the balance of linear momentum, a second-order
tensor-valued Helmholtz-type equation for the true stress as
well as a time-dependent Ginzburg-Landau equation for the
evolution of the phase field. The ODEs are the equations of
motion of the dislocations. The dislocations are modeled as
lamellae with eigenstrain that can evolve with time; the
resulting stress field is an outcome of the numerical
solution. A parallel framework was developed in order to
solve these coupled dynamics problems using the finite
element library FEniCS. We show the effect of dislocations
on phase microstructure as well as the influence of phase
microstructure on the motion of dislocations using an
illustrative example of a thermally-driven planar phase
boundary, and its interaction with a single edge
dislocation.},
