Its mechanical action is very complicated. The nonlinearity dynamics software of AUTODYN-2D/3D is adopted as a simulation platform. The each variable is analyzed one after another. The influences of variables on kinetic bullets penetrating ability are studied by changing only one variable. Numerical simulation researches have been conducted on the physical action of simulated bullet penetrating target plate. The impact rules of shear modulus, yield strength, regular pattern of hardening constants, and hardening exponent on penetration depth are obtained. Numerical simulation results indicate that the impact of shear modulus on penetration depth is not obvious. However, the impact of yield strength on penetration depth is most notable. When the yield strength of projectile body materials less than or equal to the yield strength of target board materials, projectile bodies would seriously deform instead of penetrating the target board. Both rigidification constant and rigidification index have a quite big affect on penetration depth. The penetration depth is proportional to rigidification constant. However, when rigidification index has reached at a certain value, the changes of penetration depth tend towards stability. At this time, penetration depth and rigidification index are inversely proportional to each other., authors=WANG Xiangdong¹, XIAO Yanwen², HAN Yong², WANG Haifu², authorsList=WANG Xiangdong;XIAO Yanwen;HAN Yong;WANG Haifu, authorCompany=1.

articleAbstract=模拟弹侵彻靶板的物理行为研究强冲击波产生的高温高压复合环境下的材料物性,其力学行为极其复杂。本文以AUTODYN-2D/3D非线性动力学软件为仿真平台,采用逐个变量分析法,仅改变其中一个参数研究其对动能弹侵彻能力的影响。通过对模拟弹侵彻靶板力学行为的数值模拟研究,获得了剪切模量、屈服强度、硬化常数及硬化指数对侵彻深度的影响规律。数值模拟结果表明,剪切模量对侵深的影响并不明显;屈服应力对侵深影响最明显,当弹体材料屈服应力小于等于靶板材料屈服应力时,弹体在侵彻时发生严重变形而不能侵入靶板;硬化常数和硬化指数对侵彻深度也有较大影响,侵彻深度与硬化常数呈正比关系,与硬化指数呈反比关系。,
