《复合材料层压结构的累积损伤容限可靠性分析方法》一文提出一种适用于纤维增强复合材料层压结构在遭受随机性的低能冲击下的累积损伤容限可靠性分析方法。本方法不仅将工作应力和许用强度看作随机变量而且将外来物冲击能量也视为遵循某种分布规律的随机变量。本方法可算出结构中易受外来物冲击的受压应力部位中各计算单元的累积损伤容限可靠度,从而可对该结构部位的强度可靠性作出评估。
“Method for Reliability Analysis of Cumulative Damage Tolerance of Composite Laminated Structures” A reliability analysis method for cumulative damage tolerance of fiber-reinforced composite laminates subjected to random low-energy impact is proposed. The method not only considers the working stress and allowable strength as random variables but also considers the impact energy of foreign objects as a random variable that follows certain distribution rules. The method can calculate the reliability of the accumulated damage tolerance of each calculation unit in the compressive stress part which is easily impacted by foreign objects in the structure, so that the reliability of the strength of the structure part can be evaluated.
