Research activities

PhD : Adaptive numerical simulation of damage and fracture in solid mechanics. Coupling h-adaptivity and Arbitrary Lagrangian Eulerian formulation.

Keywords : Computational Mechanics, Finite Elements Method (FEM), Large Deformation, Automatic Remeshing, Adaptive Mesh Refinement, Data Transfer, Arbitrary Lagrangian Eulerian Formulation (ALE), Metal Forming, Forging, Friction Stir Welding (FSW), Composite Materials.

Short Description : The goal of my PhD is to improve the modelling of damage and fracture in complex materials under large deformation using the in-house nonlinear Finite Element software Metafor. The strategy adopted consists in developing an automatic h-adaptive mesh refinement algorithm called “fission-fusion”, where elements can be split or merged when needed. This algorithm will then be combined with the already operational erosion algorithm and Arbitrary Lagrangian Eulerian formulation, and with a multiscale finite element squared approach currently under development.

Automatic Remeshing Procedure and Applications

The first objective in the completion of my PhD was to establish a fully automatic remeshing procedure which could be used to simulate a wide variety of mechanical processes where mesh distortion are significant.
