Smooth Particle Hydrodynamics (SPH) approach in simulating large penetration into soil

Abstrakt

A study of Smooth Particle Hydrodynamics (SPH) approach for predicting large soil deformation is presented. Theoretical basics of SPH method, including the equations governing, discussion of the importance of smoothing function length, contact formulation, boundary treatment and finally utilization in hydrocodes simulations are presented. An application of SPH to a real case of large penetrations (crater creating) into soil caused by falling mass in Dynamic Replacement Method is discussed. Limitations of Lagrangian approach, such as mesh distortion and mesh degradation are considered. Some good points as well as drawbacks of FEM, hybrid SPH+FEM approaches are presented. An examples calculated by LS-DYNA software are discussed as well.
