Abstract: A novel, meshless numerical method, called general particle dynamics (GPD), is proposed to simulate the initiation, propagation, and coalescence of three-dimensional (3D), pre-existing penetrating and embedded flaws as ...

Abstract: In this research, a novel meshless numerical method, termed general particle dynamics (GPD), to simulate crack initiation, propagation, and coalescence in rock-like materials subjected to impact loads was developed. In the ...

Abstract: This paper explores the characteristics of energy accumulation, evolution, and dissipation of sandstone samples under different confining pressure conditions in the triaxial cyclic unloading test. The characteristics of ...
