SPH(Smoothed Particle Hydrodynamics) method, which is one of the meshless analysis, has been proved as a powerful tool for structural analysis especially in hyper-velocity impact problems. Recently the method has been shown to have much potentials for general dynamic structural problems, however, the applications have not been sufficient because the fracture analysis by SPH has not fully developed. In this study crack analysis of SPH in 2 -dim has investigated to clarify the accuracy and characteristics of this method.
