Abstract

Abstract

Discrete dislocation dynamics (DDD) simulation method, as an ideal tool for bridging the gap in space and time scales between atomistic and continuum models, has made great progress in the past few decades. One prominent example is the coupling between DDD and finite element method (FEM), which leads to the capability of DDD to investigate the problems with complicated boundary conditions and multi-physics coupling effect. This work firstly reviewed the development of DDD method, and the coupling algorithm between DDD and FEM. Then, the advances and application of these methods in disclosing the microscopic mechanisms and developing the continuum models are reviewed under the extreme environment of high strain rate, high temperature, and irradiation.
- discrete dislocation dynamics,
- high strain rate,
- high temperature,
- high pressure,
- irradiation
