This paper addresses the analysis and test of the hydrodynamic ram in metallic cubic tanks with water inside. Analysis and test of hydrodynamic ram in welded metallic tanks containing water were performed to investigate the phenomena and to understand the effects on the resulting structural behavior. For a better representation of the physical phenomena, modeling of the welded edges is added to the analysis to simulate the earlier weld line fracture and its influence on the resulting hydrodynamic ram behavior. Corresponding hydrodynamic tests were performed in a modified gas gun facility, and the following panel-based examinations of engineering parameters showed that the results of the study reasonably explained the characteristics of the hydrodynamic ram.
