Linking of smoothed particle hydrodynamics method to standard finite element method and its application in impact dynamics

This paper gives a brief description of smoothed particle hydrodynamics (SPH) method. By taking the advantages of SPH and standard finite element methods, a coupled method is proposed, in which the computational model is made up of finite elements in initial time and the large distortional elements are converted automatically into smoothed particles. Numerical examples for hypervelocity impact by the coupled method show that the coupled method is a more efficient method to simulation of large deformation problems in impact dynamics.
