摘要
通过对杆式弹侵彻过程的力学分析,运用Tate理论方程和空腔膨胀理论,将侵彻过程的运动参量表达为材料力学性能的显式函数,进而将陶瓷材料差分效益因子表达为材料力学性能的显式函数,从而在理论上用材料力学性能的显式函数对陶瓷材料抗弹性能的试验数值指标进行了表达,以明确的数学形式表示了陶瓷材料对抗弹效能具有关键作用的力学性能参量.初步计算表明,该理论方法可以对陶瓷复合装甲抵抗杆式穿甲弹的防护效益做出近似的估计.
With Tate penetration theory and cavity expansion theory, the kinematic parameters of the long rod penetration and the ceramics differential efficiency factor DEF are expressed as functions of the materials properties. In this way the experimental index of the ballistic performance of armor ceramics is theoretically expressed and the key ceramic properties which have the most significant influences on ballistic performance are mathematically formulated.Calculation shows that this theoretical method can give a good ballistic performance estimate for ceramics against long-rod penetration.
