  1. Firstly on the basis of twin shear unified strength theory and spherical cavity expand theory it is established the expression about target defense force, given the equations of rod projectile penetrate and impact velocities on ceramic / composite target under the same pressure and verified through the experiment. secondly the analysis model of ceramic / grfp / steel composite multi - layer target penetrate depth employing above differential equation of target defense force, penetrate velocity and rod velocity. there are two team of experiments which testify separately the penetrate depth and effect with different length - to - diameter

    首先,基於雙剪統一強度理論和球型空穴膨脹理論建立了靶板抗力表達式,並通過壓力相等條件給出了桿式彈侵徹陶瓷復合靶板的侵徹速度與撞擊速度的表達式,最後用試驗進行了驗證;其次,利用上面的靶板抗力表達式、侵徹速度、彈桿速度的微分方程,建立了陶瓷/玻璃鋼/鋼板復合多層靶板侵徹深度分析模型,分兩組試驗對侵徹深度、不同長徑比的侵徹效果進行了驗證;最後,建立了桿式彈垂直侵徹陶瓷多層復合靶板的工程模型,給出了預測靶板抗彈性的k 。
