摘要

Analyzing the response of modern mobile platforms to ballistic impact is a challenge due to target mobility and inherent structural loads. The present work involves an experimental and numerical analysis of ballistic impact against simulated moving targets that are pre-stressed. Realization of the target movement was achieved by launching an inclined elongated projectile at an oblique target, with equal inclination and obliquity resulting in an experimental set-up corresponding to normal impact of the target plate by the projectile with a transverse velocity component. The present experimental analysis considers impact by a 0.5" calibre projectile against the aluminium target, with the objective to analyze the target damage. The modelling results reasonably agree with the experiments.
