摘要

船体板在受到楔形物撞击下会发生大的塑性变形甚至撕裂。对四周固支矩形板在楔形物垂向撞击下的塑性大变形响应进行了理论分析和试验研究;基于上限定理,提出了矩形板在线载荷或面载荷作用下发生大变形的抵抗力计算简化解析解,将理论计算结果用模型试验验证,表明所提解析方法有较好的计算精度。该解析公式对船体结构初期的耐撞性快速评估和设计具有指导意义。

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.
