18. Discrete Element Modelling (DEM)

  • A meshless particle method created to represent the constitutive behaviour of soils and rocks
  • Can deal with large deformations as well as discontinuous behaviours such as fractures
  • Applications of DEM include the analysis of the bearing capacity of soils, prediction of structural failure, and post-failure risk assessment for slopes
  • The image represents the results of hydraulic fracturing simulations, in which a highly pressurised LBM fluid fractures a DEM block that is properly calibrated
