主 题：smoothed particle hydrodynamics high velocity impact sensitivity analysis
摘 要：The modeling of high velocity impact is an important topic in impact *** to various constraints,experimental data are extremely ***,detailed numerical simulation can be considered as a desirable ***,the physical processes involved in the impact are very sophisticated;hence a practical and complete reproduction of the phenomena involves complicated numerical *** this paper,we present a smoothed particle hydrodynamics(SPH)method to model two-dimensional impact of metal sphere on thin metallic *** simulations are applied to different materials(Aluminum,Lead and Steel);however the target and projectile are formed of similar metals.A wide range of velocities(300,1000,2000,and 3100 m/s)are considered in this *** goal is to study the most sensitive input parameters(impact velocity and plate thickness)on the longitudinal extension of the projectile,penetration depth and damage crater.
