The objectives and tasks foreseen for the internship are:

  • Bibliographic study :  Exhaustive review of the literature on void shearing in single crystals, from an experimental, modelling and numerical perspectives;
  • Reference simulations : Porous unit cell simulations (similar to Fig. 2a) using FFT-based solver AMITEX_FFTP to gather a database on which the model will be calibrated;
  • Modelling : Proposition of a complete set of homogenized constitutive equations for void shearing in single crystals, implementation in MFront code generator and validation;
  • Polycrystalline simulations: Crack path prediction in polycrystalline materials based on the model developed, using FFT-based solver AMITEX_FFTP.
