摘要/Abstract

摘要： 基于复合材料三维Hashin破坏准则和相应刚度退化理论，使用基于强度理论的脱层损伤预测方法，分析了复合材料船体梁中垂和中拱状态下考虑脱层损伤模式的总纵极限强度. 提出使用折减因子对不考虑脱层的复合材料船体梁极限强度进行折减，以获取考虑脱层损伤模式的复合材料船体梁总纵极限强度的计算方法.

Abstract: Using 3D Hashin damage rules and the corresponding property degradation rules, the ultimate sagging and hogging longitudinal strength of a composite ship hull was analyzed considering the delamination damage mode based on the stress criteria of delamination. Then the degradation factor was presented which is used to predict the longitudinal strength of composite ship considering the delamination damage mode from the calculation of longitudinal strength of composite ship without considering the delamination damage model.

Key words: composite ship hull girder, 3D Hashin damage rules, property degradation, ultimate strength, delamination
