چکیده انگلیسی
Experimental investigations were carried out on Q235 steel cylindrical shell-water-cylindrical shell (CWC) structures subjected to near field or contact underwater explosion loading. All the tests were conducted in an artificial water pool detonating 50â¯g charge weight of trinitroluene (TNT) explosive. Corresponding plastic deformation of the CWC structures were measured for different structural parameters and standoff distances. Three major deformation modes including seven typical subdivided deformation characteristics were classified and analyzed considering the effect of standoff distance, shell thickness and water interlayer thickness. Microscopic analysis was performed using the SEM method to further compare two typical subdivided fracture modes with the combination of the macroscopic deformation features.
