                  摘要: 为深入分析弹体贯穿混凝土靶的破坏效应及其对侵彻过程的影响,开展了系统性理论研究工作。基于弹
               体正贯穿混凝土靶的崩落破坏现象,建立了崩落效应模型,并结合开坑效应模型与靶体阻力函数,构建了综合考虑开
               坑效应和崩落效应的侵彻理论模型,进而分析了靶厚、撞击速度对侵彻过程及靶体破坏参数的影响规律。研究结果表
               明:随着混凝土厚度减小或撞击速度增大,崩落效应对侵彻阻力及剩余速度的影响程度减弱,崩落阶段飞溅区占比增
               大,飞溅效应成为影响崩落阶段阻力的主导因素;当靶厚大于                       4.5  倍弹径时,崩落效应对靶后剩余速度的影响超过
               10%,不可忽略;开坑深度随厚度增大先线性增加(厚度小于等于                    4  倍弹径)后趋于稳定,崩落深度随厚度增大先线性增

               击速度变化对厚靶的开坑深度与崩落深度影响更为显著。所建模型能有效表征混凝土靶的破坏效应,可为混凝土靶

               Abstract:   To  further  analyze  the  damage  effects  of  projectile  penetration  into  concrete  targets  and  their  influence  on  the
               penetration process, a systematic theoretical investigation was carried out. A spalling effect model was established based on the
               spalling phenomenon observed during normal perforation of concrete targets by projectiles. By integrating this model with the
               cratering effect model and the target resistance function, a theoretical model for penetration that comprehensively accounts for
               both cratering and spalling effects was developed. By means of the presented model, the influence of target thickness and
               impact velocity on the penetration process and target damage parameters were analyzed. The results show that as the concrete
               target thickness decreases or the impact velocity increases, the influence of the spalling effect on penetration resistance and
