摘要

以带板梁为研究对象,运用极限平衡理论和数值分析手段,讨论了剪切变形为主的带板梁变形和破坏机理。内容包括,极限载荷的计算方法;不同载荷作用下带板梁各横截面的合成应力、正应力、剪应力沿腹板高度的分布及其规律;塑性变形的产生和发展过程;带板梁碰撞吸能的成分分析。所得到的结果对耐撞性结构设计、建成船舶的耐撞性评估和模型试验方案设计等都具有指导意义。

Abstract

Ultimate equilibrium theory and numerical analysis are used to discuss the deformaion and damage mechanism of a beam with band plates mainly bearing shear failure, including the method calculating extreme loading; the distribution regularity of combined stress、normal stress and shearing stress along web height at several cross-sections under different loadings; the generation and expansion of plastic deformation; energy-absorbing composition analysis of the beam with band plates in the course of collision. The results can be referenced by crashworthiness structral design、assessment of crashworthiness for a finished vessel and conceptual design for model experiments.
