A smoothed meshfree method for simulation of frictional embedded discontinuities

An enriched cell-based smoothed point interpolation method (CSPIM) is presented in this study for the numerical modelling of domains including weak and strong discontinuities. A triangular background mesh is used for domain discretisation in the proposed method. The arbitrary discontinuities, such as material interfaces and cracks, are considered in the numerical formulation by enhancing the approximation of the displacement field using...
