Abstract
A ricochet is a rebound, bounce or skip off a surface, particularly in the case of a projectile (a bullet). Many ricochets are accidental and while the force of the deflection decelerates the projectile, it can still be energetic and almost as lethal as before the deflection. The likelihood of ricochet is dependent on many factors, including projectile shape, projectile material, spin, velocity (and distance), target material and the angle of incidence. A numerical study on aluminum projectiles ricocheting off a steel plate is presented in this paper. The numerical package LS-DYNA is used to model the process of the impact of aluminum projectile on a steel plate. The simulations are carried out for a given range of projectile velocity (250 m/s to 1500 m/s) with varying impact angles. From the numerical results the ricochet angle and the ricochet velocity is predicted in terms of the incident angle and the incident velocity. The impact velocity effect on the ricochet phenomenon is studied. The numerical results are compared with available analytical solutions of the ricochet problem available in the literature.
