摘要：

We analyzed the influence of the impact energy on the damage degree of the front and rear walls and verified it by experiments. The results show that the hydrodynamic ram formed by a high-speed fragment impacting the liquid-filled vessel affects the vessel's front and rear walls and that the degree of the damage can be divided into three levels: the cracks are not observed on the front and rear walls; cracks are observed on the rear wall surface but on the front wall surface; cracks are observe on both front and rear walls and the rear wall is petal-type cracked. The maximum deformation of the front and rear walls and the total number of cracks in the front and rear walls increase with the increase of the impact energy of the fragments during the fragment impact process of the liquid-filled vessel. © 2019, Editorial Staff of EXPLOSION AND SHOCK WAVES.
