摘　　要：利用高速侵彻设备进行了不同条件下弹体高速侵彻混凝土系列实验,探讨了高速撞击条件下弹体侵彻能力、弹体侵彻稳定性、弹体变形和破坏等问题,揭示了混凝土中半流体侵彻阶段的典型特征:刚体侵彻深度上限和对应的刚体侵彻初速上限、弹道弯曲、弹体严重侵蚀且伴随弯曲/断裂等。A series of penetration tests on concrete targets by steel projectiles at normal incidence were carried out by using high-velocity penetration equipments. The penetration ability, stability and deformation/fracture of the projectiles under high-velocity impact were investigated. It is shown that transition of steel projectiles from rigid to deformable state, curved trajectory, projectile＇s erosion and bending/failure are typical phenomena observed in high-speed penetration of concrete targets.
