陶瓷复合靶板的抗侵彻模型
Penetration Models of Ceramic Composite Target
摘要
Abstract
In order to study the penetration ability of the ceramic composite target ,a damage factor is proposed to characterize the radial damage of the material in the cracked zone in the cavity expansion theory (CET ) .Based on the CET of ceramic with damage factor and the CET of metal ,the composite target composed of a ceramic tile and a semi-infinite metallic substrate is theoretically modeled .In this model ,the effects of the finite lateral boundary are ignored by assuming that the lateral dimension is infinite .Depending on the property of the penetrator-target interface to the ceramic-metal interface ,4 distinct possibilities arise .T he stress state and target resistance of each possibility are calculated re-spectively .The conclusion shows that :(1) the pressure-shear coefficient in the comminuted zone has an obvious effect on the penetration property of the ceramic ,while the tensile strength and compres-sive strength have a little effect on it ;(2) when the composite target is approximated as an infinite tar-get ,the relative size of different zones and the cavity expansion pressure are not affected .关键词
