Damage evolution and fracture characteristics of coal rock impacted by self‐excited pulse water jet under different stress loading conditions

Abstract In this paper, based on smoothed‐particle hydrodynamics‐finite element method, numerical models of plunger squeezing water at a sinusoidal velocity were established to simulate self‐excited pulse water jet (SEPWJ). RHT constitutive model was adopted to describe the damage and failure of coa...
