Abstract—

The article presents the results of a computational and experimental study on the impact interaction of structured punches corresponding to the design of Russian and foreign small arms ammunition with homogeneous steel and composite armor. Particular attention has been paid to the careful modeling of the behavior of the materials of the punch and the plate under dynamic loading.

To confirm the reliability of the calculation models used, tests have been carried out by firing at real protection samples, the results of which have shown a good agreement with the data of numerical experiments.

The developed models allow to offer effective protection at the design stage, as well as to assess the armor protection level of existing foreign samples. The calculations have been carried out using the LS-DYNA software package.

Jonson-Cook模型在冲孔机与均质板和复合板冲击相互作用的计算和实验研究中的应用

摘要-

本文介绍了结构冲头的冲击相互作用的计算和实验研究结果,这些冲头对应于俄罗斯和国外使用均质钢和复合装甲的小武器弹药的设计。特别注意的是在动态载荷下对冲头和板材的性能进行仔细建模。

为了确认所使用的计算模型的可靠性,对真实保护样品进行了点火测试,结果与数值实验数据吻合良好。

开发的模型可以在设计阶段提供有效的保护,并可以评估现有国外样品的装甲保护水平。使用LS-DYNA软件包进行了计算。
