摘要:

裂纹是复合材料层合板的主要损伤类型之一,也是造成复合材料层合板失效的主要原因。复合材料层合板发生裂纹损伤时,其内部能量结构发生变化,这些变化对外可表现为动态特性发生显著变化。因此,分别研究层合板在健康状态下和裂纹损伤状态下的动态特性,就可以分析建立裂纹损伤的诊断知识规则。

关键词: 复合材料, 层合板, 裂纹诊断, 动态特性

Abstract:

Crack is one of the most common damages in composite laminated plates,and it is the chief factor of causing failures.When there is a crack in composite laminated plates,the inner energy distribution changes,and will cause significant changes in the dynamic behaviors.Therefore,the diagnostic rules of crack failures can be developed by studying the dynamic behaviors of composite laminated plates under healthy and damaged conditions respectively.

Key words: composite material, laminated plate, crack diagnosis, dynamic behavior
