Rocks as natural building materials have been widely used in protective engineering and military fortification/installations. Hence, it is of great significance to carry out studies on the penetration of rock targets by projectiles. This paper contains two parts. The first part is an overview of the previous work with emphasis being placed on the formulas for the depth of penetration; the second part is a further development of the penetration model proposed by Wen by modifying the shear strength (Y) which has been found to be a function of both projectile diameter and target unconfined compressive strength based on the experimental observations. It is shown that the model correlates well with the penetration data for the limestone targets impacted by ogival-nosed projectiles.

对岩石在刚性弹丸撞击下的侵彻问题进行了理论研究。文章包括两个部分。首先,对常用的预测岩石在刚性弹丸撞击下侵彻深度的方程进行了简单回顾和评论;然后,在实验观测的基础上,对最近发表的一些预测在刚性弹丸撞击下,混凝土和土壤的侵彻公式进行了修正,推导出一个较为合理的剪切强度表达式。拟合结果表明:该模型与Frew、Forrestal和Hanchak所得到的石灰岩侵彻的实验数据吻合得很好。

对岩石在刚性弹丸撞击下的侵彻问题进行了理论研究。文章包括两个部分。首先,对常用的预测岩石在刚性弹丸撞击下侵彻深度的方程进行了简单回顾和评论;然后,在实验观测的基础上,对最近发表的一些预测在刚性弹丸撞击下,混凝土和土壤的侵彻公式进行了修正,推导出一个较为合理的剪切强度表达式。拟合结果表明:该模型与Frew、Forrestal和Hanchak所得到的石灰岩侵彻的实验数据吻合得很好。

Rocks as natural building materials have been widely used in protective engineering and military fortification/installations. Hence, it is of great significance to carry out studies on the penetration of rock targets by projectiles. This paper contains two parts. The first part is an overview of the previous work with emphasis being placed on the formulas for the depth of penetration; the second part is a further development of the penetration model proposed by Wen by modifying the shear strength (Y) which has been found to be a function of both projectile diameter and target unconfined compressive strength based on the experimental observations. It is shown that the model correlates well with the penetration data for the limestone targets impacted by ogival-nosed projectiles.
