| 摘 要： | 论述了基于冲击威胁概念的复合材料结构冲击损伤容限可靠性分析方法。采用该方法对国产T300/5405和T300/QY8911复合材料层压板、加筋板以及国产T300S/9511、T800/9511和T300/9512层压板的冲击损伤容限可靠性进行了分析和评估。实例分析表明,由于所采用的方法考虑了冲击威胁分布,可以更好地发挥复合材料结构的冲击损伤容限性能。

| Abstract: | An impact damage tolerance reliability analysis method was discussed for composite structures by introducing an impact threat concept. The method was applied to the damage tolerance reliability evaluations of domestically produced composite laminates and stiffened panels such as T300/5405, T300/QY8911, T300S/9511, T800/9511 and T300/9512. The example reliability calculations indicate that the damage tolerance capability of composite structures could be taken fully since the impact threat distributions are considered in the present method. |
