... factor method may give over-conservative results. The underwater explosion loads on the subsea pipelines have been numerically simulated by the CEL method. Three different explosion distances have been investigated, which are 2.5 m, 5 m, and 15 m. Based on the results, the following...

... to underwater explosion were studied through a combination of experimental and numerical methods. First, a series of comparative underwater explosion tests were carried out on the scaled empty and fluid-filled double cylindrical shells. Then, more detailed numerical simulations were developed to give more...

...Yong Chen; Yu Wang; Zhiyi Zhang; Hongxing Hua In a study conducted by the U.S. Navy [ 9 ], it was revealed that if a steel panel was covered with a low density layer of glass microspheres, the damage caused to the steel panel would increase when it was subjected to underwater explosion. However...

... at first. Table 2 shows the central deformation of the endplates of main hull sand-filled test models subjected to underwater explosion. The central deformation of the back endplate is much larger than that of the front endplate after two times sequential shocks generated by detonation of 1 kg spherical...
