| 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. |
