| 摘 要： | 为研究不同强度等级的高与超高性能钢纤维混凝土材料的抗侵彻性能,采用25 mm口径弹道炮开展了初速度500～850 m/s的正侵彻实验,利用高速摄影系统记录了弹体的着靶姿态及靶体的动态破坏过程,采用非线性有限元方法对侵彻全过程进行了数值模拟.实验结果表明,随着混凝土强度等级的提高及钢纤维掺量的增加,侵彻深度略有减小,但这种差距随着强度等级的提高越来越小;随着纤维掺量的提高及侵彻速度的降低,材料破坏程度明显减弱.

| Abstract: | To study the anti-penetration performance of high and ultra-high performance steel fiber reinforced concretes(SFRC),penetration experiments with projectile velocities of 500~850 m/s were performed by using a ballistic gun with 25 mm caliber.The target impact attitude of projectile and the dynamic destruction processes of all targets were observed by means of a high-speed camera.The whole process of projectile penetrating into target were simulated by nonlinear finite element.Experimental results show that t... |
