摘要
在实验的基础上 ,对预扭转钨合金长杆弹提出了一个唯象的本构模型和破坏准则 ,并针对预扭转钨合金长杆弹侵彻厚钢靶进行二维有限元计算 ,得到了侵彻过程中的主要物理图象和曲线 ,进而对计算结果进行了分析讨论。计算结果表明 。
Based on the experiments, a constitutive model and failure criterion are proposed for the pre-torqued long rods of tungsten alloy. The pre-torqued long rods of tungsten alloy penetration in the steel targets are simulated numerically. The main penetrating patterns are obtained and the results of simulation are discussed. The results of simulation agree with the experimental results very well.
