考虑脆性材料在高速弹体的侵彻下会发生破碎这一特性，将靶体材料划分为弹性-裂纹-破碎三个响应区，利用静态空腔膨胀理论求出了空腔膨胀压力，即修正的流体动力学模型（A-T模型）中的靶体阻力R_t。分析了压剪系数对靶体阻力和靶体应力场的影响。利用A-T模型求出了钨杆弹以1.5~4.5 km/s的速度撞击靶体时的侵彻深度，并与实验结果及其他研究者的结果进行了比较。

Brittle materials can be pulverized near the tip of the penetrator under high-velocity impact. This paper considers the pulverization of brittle materials and divides the target into the pulverized, cracked and elastic regions, and derived the cavity expansion pressure, viz. target resistance R_t of A-T model (modified hydrodynamic model) based on static cylindrical cavity expansion theory. The influences of the pressure-shear coefficient on R_t and stress fields are discussed. The depth of penetration is calculated using A-T model for a tungsten long rod impacting brittle target at 1.5~4.5 km/s. The calculated results of this model are compared with the experimental data and the results of other models.

Key words

brittle materials / penetration / cylindrical cavity expansion theory / target resistance
