Research on Oblique Penetration of Projectiles into Targets of Different Materials

In order to study the trajectory deflection of projectile penetrating obliquely into different materials, Lagrange algorithm LS-DYNA was used simulate three-dimensional model. The impact angle is 70°, concrete target and soil are penetrated respectively. state target, strain nephogram stress under maximum overload obtained. curves penetration depth, velocity, energy analyzed. results show that: in oblique penetration, projectile's deflects more process entering then less; small a certain distance after it, but it becomes larger when fast out target.
