摘　　要：本文旨在对万向接轴本体两类缺陷，即表面半椭圆裂纹及心部椭圆裂纹进行脆断安全评定。采用确定性断裂力学理论及概率断裂力学理论分别建立了确定性及可靠性评定模型，为制定相应压下制度下缺陷的安全评定及可靠性分析规范打下了基础。This paper is focused on establishing models for brittle fracture assessment ofⅠand Ⅲ mixed-mode semi-elliptical crack and corner crack existed in the axis of 1300 type blooming mill. Two different approaches are employed to develop the assessment model.One is based on deterministic fracture mechanics, resulting in deterministic models.Reliability interference assessment models are also proposed from probabilistic fracture mechanics.These models may be used to lay down safety criteria free from brittle fracture.
