Discrete dislocation dynamics is a numerical tool developed to model the plasticity of
crystalline materials at an intermediate length scale, between the atomistic modeling and the …

A unified model coupling 3D dislocation dynamics (DD) simulations with the finite element
(FE) method is revisited. The so-called Discrete-Continuous Model (DCM) aims to predict …

A new and efficient formulation of the Discrete-Continuous Model (DCM) for the simulation of
3D dislocation dynamics in complex finite or periodic volumes is presented. As in previous …

In this paper, an extension of the DDD-FFT approach presented in [1] is developed for
heterogeneous elasticity. For such a purpose, an iterative spectral formulation in which …

Unraveling the deformation mechanism of materials under extremely high strain rate is
critical from both scientific and engineering viewpoints. The elastodynamic effect of 3D high …

Mesoscale simulations of discrete defects in metals provide an ideal framework to
investigate the micro-scale mechanisms governing the plastic deformation under high …

Multiscale dislocation dynamic simulations are systematically carried out to reveal the
dislocation mechanism controlling the confined plasticity in coated micropillar. It is found that …

Ce présent travail s' inscrit dans le cadre de la modélisation multi-échelles de la plasticité
cristalline des superalliages monocristallins à base nickel. Dans ce contexte, une transition …

The resolution of reaction filters for intermediate-energy heavy-ion collisions based upon
charged-particle and neutron multiplicity measurements with 4π coverage is compared for …

Fracture toughness in materials is not only controlled by macroscopic parameters but also
by the microstructure. The defects of the crystalline structure such as voids, inclusions or …
