Simulation of projectile-wall collision by using smoothed particle hydrodynamics (SPH)

This paper presents the high velocity impact case study of projectile-wall collision by employing smoothed particle hydrodynamics (SPH). SPH is a method, which is based on the particles that have their own properties and governing equations. SPH has the capability to simulate high velocity impact, excessive deformation and breakage. Among parameters explored in this study are stages of failure, perforation limit and effects of variations of yield strength and velocity impacts. The velocity ranges were from 100 m/s up to 2000 m/s, and it was observed that when the velocity reached 500 m/s the target was perforated by the projectile. The effects of the yield stress towards deformation behavior and von misses stresses for both target and projectile were also investigated and presented in this paper.
