Abstract
The damaging effect and residual strength of ships under the near-field underwater explosion loads has remained as one of the most crucial subject in the field of vessel research. In this paper, the struc⁃tural response under explosive loads is simulated based on the common FEM software by assuming a typi⁃cal near-field condition of underwater explosion. Loss of the modulus for typical sections is then analyzed according to the crevasse and plastic deformation results of near-field blast, and the loss is within 8%~10%. The wave bending moment and still water bending moment are also calculated after the buoyancy re⁃distribution. Finally, the residual strength in the damaged cases is analyzed simultaneously for the near-field underwater explosion combined with military regulations. The results show that the vessel still meet the requirements of residual strength under torpedo attack.关键词
