摘要
在确定性袭纹扩展模型的基础上,建立了疲劳裂纹扩展的随机模型。考虑裂纹扩展引起的强度衰减,建立了实用的动态可靠性分析模型。
A stochastic crack growth procedure which based on the determined crack growth model is presented in the paper. A dynamic reliability model is gven, in which the strength deterioration that caused by the propagation of crack is considered.
