摘　　要：根据 Forrestal 提出的侵彻模型,计算了钻地炸弹在正常撞击混凝土目标之后的侵彻深度。本文使用了一种近似的分析方法—空穴膨胀理论.该理论把弹头部与靶标接触面视为球形空穴膨胀表面,然后再建立空穴表面膨胀应力与空穴膨胀速度间的关系式。为验证该模型的有效性,我们将计算结果与美军装备的钻地弹的侵彻威力进行了对比,结果表明两者符合良好。We calculated penetration depth for ogivel-nose projectiles that penetrated concrete targets after normal impact,According to closed-form penetration equations by Forrestal developed.We use the pherical,Cavity- expansion approximation.Normal stress on the projectile nose is taken as the stress at the cavity surface associated with the distributed expansion velocity at the nose-target interface caused by projeatile penetration.To verify our model,we calculated air bombs penetration Depth of U.S.A are equippe...
