| Abstract: | In order to find the weakness of the structures, the deformation of models and the dimension and shape of the breach are studied and analyzed on the basis of the underwater contact explosion experiment with three element structure models of vessel. A new factor is defined to measure the relative stiffness of the stiffener in a stiffened plate, and a coefficient of the equation to estimate the length of the breach is found out. Simultaneously, the experimental data such as an ultimate strain of material are presented. |
