Problem Statement

  • Generate spectral crystal plasticity database for hexagonal materials
    • Locate and modify crystal plasticity codes for different input parameters
      • Selected slip and twin families
      • c/a ratio ??

  • Validate the crystal plasticity codes with existing results in literature or from our group

  • Generate and validate the database against FEM simulations

  • Integrate with FEM

Questions

  • Building Crystal Plasticity for Hexagonal Systems
    • What are the minimum number of parameters requried to capture the deformation of the generic hexagonal lattice?
    • How does the c/a ratio relate to the slip acitivity?
    • In which alloys does twinning play an important role?
