摘要:
该文结合某型陶瓷复合装甲的侵彻实验,利用三维非线性动力有限元程序LSDYNA3D,建立高速钨质长杆弹对多层陶瓷复合装甲侵彻的有限元分析模型,描述了侵彻全过程的有关物理和力学现象,并与实验进行对比,数值结果与实验结果吻合,对进一步研究复合装甲防护及弹体侵彻性能具有一定的参考价值。
Abstract:
W ith respect to an actual exper imen,t finite e lem ent simulat ion using LS-DYNA3D is perfo rmed to invest igate the responce of a ceram ic integral armor pene trated by h igh-ve loc ity long rod of tungsten alloy. The main penetrating patterns are obta ined and discussed. The simulatee l results are in good agreement w ith the experim ental resu lts. It g ives useful insight into the investigat ions on the pro tective composite systems and rod projectiles.
