This paper focuses on the tensile cracking mechanisms of rock masses containing random fissures and conducts research based on the meshless numerical method. In view of the shortcomings in traditional research on rock crack propagation, such as the difficulty of experiments in reflecting stress changes, the inapplicability of theoretical research to complex geometric conditions, and the limitations of existing numerical simulation methods, this paper proposes an improved Smooth Particle Hydrodynamics (SPH) method. The traditional SPH smooth kernel function is rewritten, a parameter к that can represent particle failure is introduced, the Mohr-Coulomb criterion is combined to judge particle failure, and the control equations are
