摘要
对近年来国内外在结构元件疲劳断裂可靠性分析的经典模型的简要综述基础上,结合新的数学 分析方法,重点分析和讨论了元件疲劳断裂可靠性分析的新方法和新模型。包含脆性断裂和韧性断裂的随机 有限元法模型、随机模糊混合可靠性模型、概率与非概率混合可靠性模型、基于遗传算法和神经网络的可靠 性模型和应变疲劳可靠性模型。
In this paper,based on simple summarization of some classive models for structure elements fatigue and fracture reliability analysis.New structure elements fatigue and fracture reliability analysis methods and models are provided and discussed using new mathematical analysis techniques, including stochastic finit element model including brittle fracture and tenacious fracture,hybrid random and fuzzy model,hybrid probabilistic and nonprobabistic model,reliability model based on Genetic Algorithms and Neural Network,and strain-based fatigue reliability model.
