大量实验研究表明,复合材料损伤容限设计主要是一个静力问题,基于此,本文用履盖的方法对局部损伤进行工程化处理,研究了固有损伤和冲击损伤对复合材料性能的影响;然后将这一处理方法引入到复合材料的可靠性分析中去,得到了带损伤的复合材料结构的可靠性分析模型,最后用两个算例检验了本文提出的方法,得出的结论与定性分析相同,对工程设计可以提供定量的指导。 A large number of experimental studies have shown that the damage tolerance design of composite materials is mainly a static problem. Based on this, the local damage is engineered by the method of tracking and covering, and the effects of inherent damage and impact damage on the properties of composite materials are studied; This method was introduced into the reliability analysis of composite materials, and a reliability analysis model of the composite structure with damage was obtained. Finally, two examples were used to test the proposed method, and the conclusions and qualitative analysis were obtained. In the same way, quantitative guidance can be provided for engineering design.
