Abstract

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.
