Abstract
SPH had been studied in the field of compressible fluid dynamics. Recently, SPH was extended to simulate the dynamic structural problems including failure. SPH is truly meshfree method based on the Lagrangian calculation. It is difficult to simulate failure and fracture phenomena for the finite element method. The SPH is appropriated to analysis including failure and fracture. This paper presents 3-dimesional smoothed particle hydrodynamics (SPH) analysis for damage caused by impact such as analysis of cerebral contusion with breaking a skull or a front glass shield of a car or spall caused by hypervelocity impacts. The total analysis including fracture and failure are calculated in the present paper.
