Numerical Simulation of Truncated Cylindroconical Projectile Penetrating Thin Target

摘要

Based on the material mechanical behavior investigation of projectile and target, the process of truncated cylindroconical projectile penetrating thin steel target with oblique angle of 0° and 45° was simulated by LS-DYNA. The interaction between projectile and target at normal impact can be divided into two phases, the deformation and failure of projectile and target. The tumbling movement of projectile at 45 ° oblique penetration varies with impact velocity.
