细长弹体侵彻混凝土的机理研究

ON MECHANISM OF SLENDER PROJECTILE PENETRATING INTO CONCRETE

通过侵彻模型试验,得到细长弹体侵彻混凝土的机理。整个侵彻过程可分为漏斗状弹坑形成阶段和坑下侵彻阶段,给出细长弹体侵彻混凝土的预计计算方法并验证其可靠性。

In this paper the mechanism of slender projectile penetrating into concrete is gained by using the scale penetration experiments. The whole penetrating process can be divided into the phase of funnel crater抯 formation and the phase of penetration under the crater. The calculation methods for predicting penetration of slender projectile into concrete are suggested and its reliability is verified.
