This research activity deals with multiscale modelling of crystal plasticity with a special focus on discrete dislocation simulations (DD code). In the DD code developed at SIMaP, the dislocation lines are simulated as 3D line defects embedded in an elastic continuum medium. The scale of a typical simulation box being of the order of 10 µm³, the DD code is ideally located between the atomistic simulations of molecular dynamics and the finite element methods used to treat the continuum mechanics. DD simulations are thus an interesting numerical tool to use when information from the lowest scale has to be accounted for at the continuum level.
