Discrete dislocation dynamics simulations: application to multiscale modelling of crystal plasticity (www.numodis.com)

Crystal sheared by Frank-Read loop mechanism

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.

Cavitation erosion simulations:

The objective of this activity developed in collaboration with LEGI, is to compute mass loss of materials repeatedly impacted by bubble collapses. During the past few years we have been addressing this issue in three ways.

(i) Inverse FEM modelling: A specimen was exposed to cavitation during a few minutes and the individual pits printed on the surface were measured. An inverse FEM analysis is then conducted in order to find the pressure loads that could generate similar pits. This gives an estimation of the flow aggressiveness.
(ii) CFD/FEM coupling: Computional Fluid Dynamics and Finite Element codes are coupled in order to compute the damage cumulated in the solid after the collapse of many bubbles in vicinity of the liquid/solid interface.
(iii) SPH simulations: Smoothed Particle Hydrodynamics simulations are developed in order to account in a single code for both a compressive model for the fluid part and a elasto-visco-plastic damage model for the solid part.
