					    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。Abstract: Aseriesofpenetrationtestsonconcretetargetsbysteelprojectilesatnormalincidencewere carriedoutbyusinghigh-velocitypenetrationequipments.Thepenetrationability,stabilityanddeformation/ fractureoftheprojectilesunderhigh-velocityimpactwereinvestigated.Itisshownthat transitionofsteelprojectilesfromrigidtodeformablestate,curvedtrajectory,projectileserosion andbending/failurearetypicalphenomenaobservedinhigh-speedpenetrationofconcretetargets.-
