Experimental study on the deformation and damage of cylindrical shell-water-cylindrical shell structures subjected to underwater explosion

Computational analysis of bubble–structure interactions in near-field underwater explosion

“…1. The explosion is a far-field explosion and the only loading the structure undergoes is the planar shockwave from the explosion (e.g., [2][3][4]). 2.…”

“…The dynamic response and failure of structures under shock waves produced by far-field explosions have been studied extensively in the past. For example, various studies (e.g., [2][3][4]) have shown how explosions can cause damage or collapse on various structures, including ship hulls, underwater pipelines, and submarines. These large pressure waves can cause large plastic deformations in a structure and can easily cause severe damaging.…”

A semi-analytical method for the dynamic analysis of cylindrical shells with arbitrary boundaries

“…As an important structural component, the cylindrical shells have been widely used in ship construction and marine engineering, such as autonomous underwater vehicles, deep-ocean submersibles, subsea pipelines and nuclear facilities for their transportation ability, convenient storage and good load capacity (Gupta et al, 2016;Wu et al, 2018;Zhang et al, 2015a). These structures usually suffer from extreme loads including ocean currents, waves, and wind etc., resulting in vibration and damage of the structures (Zhang et al, 2015b).…”
