Abstract

Abstract: We introduce several improvements on key numerical techniques,especially for free surface identification and solid boundary handling method.They make K2_SPH simulating breaking waves successfully.It includes running-up,over-turning and breaking processes.Numerical test of violent tank sloshing shows that K2_SPH method is more accurate and reliable than traditional smoothed particle hydrodynamics(SPH) method for wave profile and pressure distribution.

Key words: smoothed particle hydrodynamics, K2_SPH, meshless method, breaking wave simulation

A modified PUFF equation of state is proposed with considenation of both non-linear volume change and anisotropic strength of material under compression and dilation.Taking 2-D impact of orthotropic material and thermal shock wave under X-ray radiation as examples,a finite element program is developed.The mean stresses obtained by traditional and modified PUFF equation of state are compared.They are obviously different at low compression and tension states.With increase of stress,they tends to be consistent gradually.
