Abstract
In order to describe the plastic behavior of crystalline materials containing structural heterogeneities and/or under complex loadings, a new non local method that incorporates both dislocation properties and a rigorous treatment of boundary value problems is proposed. This new computer model makes use of a coupling between two different types of three-dimensional simulations : a Finite Elements code and a simulation of dislocation dynamics at the mesoscopic scale. The simulation technique is briefly presented and is illustrated by preliminary tests on the plastic deformation of copper single crystals at small strains.
