摘要
One of the most functional standard numerical methods for studying of material deformation and failure is the finite element method (FEM). In some cases, the FEM method cannot perform well in the simulation of some behaviors of rocks and soils due to tangling of the meshing process even in the case of employing the updated Lagrangian method. Researches indicate that the smoothed particle hydrodynamic arising from the fast development, computational sophistication, and emergence of mesh-less particle modeling techniques present proper solutions for problems that cannot be simulated by traditional finite analytical techniques. The advantages of applying this method are simplicity of concept, relative simplicity in combination with modern physics, and particularly its potential in the study of large deformations and failures. This work deals with the advances in this mesh-free technique for numerical analysis and modeling of soil and rock failure.
