Abstract:
When simulating cohesive granular materials using smoothed particle hydrodynamics (SPH), tensile instability often arises, characterized by particle clustering and non-physical fractures. In two-dimensional scenarios, this issue is typically addressed by the artificial stress method, which introduces repulsive forces between particle pairs. However, extending this approach to three dimensions is considered complex due to the requirements of matrix diagonalization and coordinate system rotation....     »
