摘要

根据岩石（混凝土）类材料在射弹侵彻时所产生的变形和破坏现象，考虑靶体材料的可压缩性，建立靶体材料变形的数学模型，得出射弹在靶体中侵彻时所受的阻力，再根据牛顿运动定律建立射弹的运动方程，用增量方法求解方程，得到弹体侵彻过程中的参数及侵彻深度。与经验公式相比较，说明该方法具有实用性和可靠性。

Abstract

The mathematical model of deformation and failure of rock (concrete) is presented based on the phenomena that projectile penetrates into rock (concrete)

considering the compressibility of the target material. The resistance of projectile in the process of penetration has been obtained. The motion equation of projectile is gained according to the Newton’s law of motion. The parameters and penetration depth of penetration are obtained; the equation is solved by using increment method. By comparing the result of calculation with ones from the empirical formulas

the practicability and reliability of the method are proved.
