摘要
详细讨论了ΔK、ΔKth的分布特性,提出了适用于含裂纹构件无限寿命可靠性分析与设计的ΔK-ΔKth干涉模型,给出了承受交变载荷的构件中初始裂纹不继续扩展的可靠度,并在给定的可靠度下,确定出构件中所允许的最大初始裂纹尺寸。
After detail discussion on the distribution characteristics of ΔK and ΔK th ,interfering model of K-ΔK th is proposed,which is suitable for the reliability analysis and design of unlimited lifespan cracking members.In member under exchanging load,the nonextending reliability of initial crack is determined.With given reliability,the allowable maximum of the initial crack dimension is calculated.
