Three-dimensional discrete dislocation dynamics (DDD) has been used successfully to investigate different aspects of plasticity. An investigation of thin-film plasticity with the help of these DDD schemes requires detailed modelling of the interfaces

Mesoscale simulations have recently been developed in order to better understand the collective behaviour of dislocations and their effects on the mechanical response. Those simulations deal with dislocations discretized into segments which are allow

In order to better understand how an indent-induced plastic zone forms, the experimental conditions associated with nanoindentation testing on f.c.c. crystals are modeled, using a combination of three- dimensional discrete dislocation simulation and

Le but de simulations de dislocations 3D est de fournir un outil de comprehension permettant d'aborder la modelisation de la plasticite des cristaux de maniere plus realiste. Pour ce faire, la comparaison avec des tests de laboratoire est necessaire,

Nanocomposites obtained by casting a mixture of a latex and an aqueous suspension of cellulose whiskers have been studied. Their mechanical properties (e.g. shear modulus) are found to increase by more than three orders of magnitude in the rubbery st

A three-dimensional (3D) dislocation simulation has been developed in the last few years in order to fill the gap between atomistic simulations and the more macroscopic approaches. The specific role of such a simulation is to combine all mechanisms r

In some Al alloys, the damage observed is often associated with fragmentation and decohesion of hard particles. A non-uniform angular distribution of particles can induce an anisotropic damage evolution with respect to the strain paths. A model is-pr
