摘要

摘要: 基于描述材料在高速高压冲击下的动态行为的方程，建立了相应的冲击波前为一般曲面的方程．通过分析，针对混凝土材料，提出了可给出弹体减速度时间历程解析解的法向膨胀理论．它不仅适用于球形弹头和柱形弹头，也适用于其他类型的弹头，如锥形弹头和卵形弹头等；它不但适用于垂直侵彻，也适用于斜侵彻．

Abstract: Based on the equations which describe the dynamic behavior of material under high-velocity and high-pressure shock,corresponding equations at shock front whose surface was general space curve surface were established.For concrete material,a normal expansion theory was proposed by which some deceleration about time history of the projectile can be analytically given.This normal expansion theory is not only suitable for spherical and cylindrical-nose projectile,but alsosuitable for other general nose projectile,for example conical nose or ogive-nose.And it is not only suitable for perpendicular shock but alsosuitable for oblique shock.
