Although Finite Element simultions are routinely used at GPM2, implementing Discrete simulations is a specific feature of the group. In-house codes have been developped for several years based on Discrete Dislocation Dynamics (TRIDIS, NUMODIS) or Discrete Element Methods (dp3D). More recently, Smoothed Particles Hydrodynamics (SPH) simulations have been developed for the study of cavitation erosion. These codes provide powerful tools for investigating plasticity, damage and fracture mechanisms.
