摘要
综合采用SPG-结构化ALE流固耦合和重启动的数值计算方法,分析了动能攻坚战斗部对钢纤维混凝土结构的侵爆复合破坏效应.结果表明:当战斗部命中结构右侧边缘柱中部和上方顶板中心时,边缘柱和顶板断裂变形,但整体结构稳定,少量冲击波绕射进入结构内部,对内部人员不产生威胁;命中结构下方墙体时,墙体发生贯穿破坏并向内倾覆,大幅削弱结构的正面防御能力,结构内冲击波超压可对距离命中位置0.55 m范围内人员造成致命伤害.
Abstract
The combined damage effect of kinetic energy attack warhead on steel fiber reinforced concrete structure is analyzed by using SPG-structured ALE fluid-structure coupling and restart numerical calculation method.The results show that when the warhead hits the center of the right edge column and the top plate,the edge column and the top plate will fracture and deform,but the whole structure is stable,and a small amount of shock wave will enter the inside of the structure,which will not pose a threat to the personnel inside.When the wall below the structure is hit,the wall will cause penetrating damage and overturn inward,greatly weakening the frontal defense capability of the structure,and the shock wave overpressure in the structure can cause fatal injury to personnel within 0.55 meters from the hit position.
