Numerical methods for fracture mechanics (2D and 3D):

Ductile Fracture

Damage Plasticity Model linked to XFEM for shell structure.

extended finite element method (XFEM)

  • Coupling XFEM with the Spectral element method (high order elements).
  • Meshfree method computation, coupled with XFEM: crack branching.
  • XFEM applied in shell elements: 4-node (BT) and 3-node (DKT) shell elements.
  • Improvement of the discretization near crack tip: enrichment developed with particular discretization strategies:
    - Crack tip enrichment used in XFEM and explicit code: View the WCCM 2008 presentation
    - Study of the stability with such enrichment strategy.

    Stress intensity factors computation

    Applied to graded material and thermal loading.
    Stability study of a crack in a heated strip.

    Numerical examples:

  • 2D and 3D crack propagations


  • Wave propagation with Spectral element method:

    Computational fluid mechanics:

    Development of a personal CFD code: steady case and incompressible flow so far; the purpose will be to couple with the solid code to deal with fluid-structure interaction.
    Numerical example: Cavity flow and a rotating cylinder in a flow
