摘要
利用动态特性对复合材料层合板的脱层损伤进行无损检测,是一种方便、实用的方法。复合材料层合板发生脱层损伤时,其内部微观结构、应力分布以及材料性能参数都会发生变化,这些变化会引起材料的动态特性发生显著的变化。因此,分别研究层合板在健康状态下和损伤状态下的动态特性,就可以分析建立脱层损伤的诊断知识规则。
It is a convenient and practical method using dynamic behaviors to diagnose delamination in composite laminated plates. When there is a delamination in composite laminated plates, the inner microcosmic structure, stress distribution and material feature will change, thus causing the dynamic behaviors of the materials to change remarkably. Therefore, the diagnostic rules of delamination failures can be developed by studying the dynamic behaviors of composite laminated plates under healthy and damaged conditions respectively.
