Abstract

Discrete dislocation dynamics (DDD) is recognized as a bridge linking finite element modeling (FEM) and atomistic dynamics, and it has been used to reveal the plastic behavior of materials at micro-scale. In this paper, a concurrent two dimensional (2D) multiscale simulation framework, truly physical coupling DDD and FEM, is developed based on the secondary development of ABAQUS. This includes Fortran coding of UMAT, UEXTERNALDB and URDFIL and other user-defined subroutines. Besides basic dislocation mechanisms like dislocation annihilation, dislocation nucleation and interaction with obstacles, the three-dimensional dislocation mechanisms such as dislocation junctions is also incorporated in this model. Furthermore, the multiscale model was used to perform the compression processes of single crystal Aluminum. The results indicate that the proposed model can well simulate dislocation evolution under the applied loading condition. The dislocation distribution and densities that reflects the material microstructure evolutions can be obtained by statistical analysis of the simulation results.
