Abstract: In this paper, calculation and analysis of dynamics are made on penetration of a thin plate by truncated projectile for the sake of fuze designing. The impact velocity ranges from 200m/s to 1000m/s, including both low and high impact velocity. The target plates includethin aluminum plate and plywood.Because the strength effect of target plates is considered in the establishment of the dynamic model the problem is here seffled where some previous models are not suitable for low-velocity impact, for example: M. Zaid and B.Paul’s modelstl][2]. From comparison of inertial effect with strength effect, zaid and paul’s test conclusion, is theoretically proved viz: only when the impact velocity is more than 500m/s can the strength effect be neglected, otherwise it can not be ignored.
