Small Fragile Armour-piercing Damage Characteristic Research

Fragile armour-piercing shell is a new type of multifunctional slim ammunition, the light armor multilayer target has high damage effect. This paper from the fragile material characteristic and the end effect aspects, the fragile type either in armor process shot core stress state and the fragile material mechanical performance requirements, with a theoretical analysis of the mechanical wear armor damage characteristics and fragile play core broken mechanism and fragment aftereffect. Through the fragile type either analog target penetration damage test results show that the fragile either limit penetration rate is higher, lower than ordinary armour piercing shell and tungsten carbide hard core either; The target velocity on the damage effect has great influence, in the play core certain premise, fragile either to the target damage effect depends on the target speed.
