Ballistic performance of tungsten fiber-reinforced metallic glass composite in the long rod oblique penetration/perforation

  • 摘要: 基于钨纤维和金属玻璃基体的实际分布特性,建立复合材料弹体的细观有限元几何模型,采用修正的热力耦合本构模型来描述金属玻璃基体的高强度和高剪切敏感性,结合相关的斜侵彻/穿甲试验,开展复合材料长杆弹斜侵彻/穿甲钢靶的三维有限元模拟,与钨合金弹进行对比分析,讨论弹靶变形和破坏特征,分析了撞击倾角、撞击速度等因素对复合材料弹体侵彻/穿甲“自锐”行为以及弹道特征的影响。结果表明,在斜侵彻/穿甲条件下,由于弹体头部受力的非对称特征,弹头逐渐锐化为非对称的尖头构型,同时弹道偏转,复合材料弹体的“自锐”性能以及侵彻/穿甲能力下降。撞击速度对斜侵彻/穿甲条件下弹体的“自锐”特征及弹道行为有显著影响,低速撞击条件下,撞击倾角越大,弹体侵彻性能越弱;当倾角增大到50°时,撞击速度小于900 m/s的弹体均难以有效侵彻靶板;倾角进一步增大时,弹体容易跳飞。
