摘要
利用LS-DYNA有限元程序,用弹塑性模型建立材料模型,对高速弹丸侵彻均质钢板问题进行了数值模拟,并与测试结果进行了比较,说明了有限元分析的有效性,为引信设计提供参考。
Using LS - DYNA finite element method, the material model is built with plastic_kinematic model and the numerical simulation about the process of high speed projectile penetrating homogeneous steel target is made. The simulated data is compared with the tested result to verify the effective of the finite element analysis, and give referrence to fuzing design.
