A 3D mesoscopic approach for discrete dislocation dynamics

by O. Politano, J. M. Salazar
Materials Science and Engineering A ()

Abstract

In recent years a noticeable renewed interest in modeling dislocations at the mesoscopic scale has been developed leading to significant advances in the field. This interest has arisen from a desire to link the atomistic and macroscopic length scales. In this context, we have recently developed a 3D-discrete dislocation dynamics model (DDD) based on a nodal discretization of the dislocations. We present here the basis of our DDD model and two examples of studies with single and multiple slip planes. ?? 2001 Elsevier Science B.V. All rights reserved.
