Abstract

Ship plating can experience large plastic deformation and even tearing under lateral impact by a wedge.In this paper, theoretical and experimental studies on the response of large plastic deformation were conducted.Based on the upper bound theorem, a simplified analytical method for the resistance of a clamped rectangular plate subjected to line or rectangular area load was proposed.Analytical calculation formulae were derived and verified with model tests.The results show that the analytical method can provide a guidance for crashworthiness design of ship plating.
