Numerical modeling of blasting

Challenges

  • A good material model for the mountain
  • Simulaton of the mountain's reaction to high pressure and subsequent damage
  • Material models for explosive
  • High resolution model

Evaluation of numerical codes and methods

  • LS-DYNA code
  • Euler and Lagrange element formulation
  • A method for interpreting the fragmentation based on the estimated damage
  • Various constitutive models such as RHT model
