基于动态空穴膨胀模型，提出了一个无量纲的通用公式，用于预测非变形弹丸在几种介质中正撞击时的侵彻深度。建议的公式取决于两个无量纲数，并显示出良好的协议与金属，混凝土和土壤的头部形状和冲击速度的范围内的渗透试验。该公式的有效性要求侵彻深度大于弹体直径和弹头长度，而弹体保持刚性，不发生明显的变形和损伤。(C)2002爱思唯尔科技有限公司版权所有。
A general non-dimensional formula based on the dynamic cavity-expansion model is proposed to predict penetration depth into several mediums subjected to a normal impact of a non-deformable projectile. The proposed formula depends on two dimensionless numbers and shows good agreement with penetration tests on metal, concrete and soil for a range of nose shapes and impact velocities. The validity of the formula requires that the penetration depth is larger than the projectile diameter and the projectile nose length while projectile remains rigid without noticeable deformation and damage.
