Probabilistic assessment of fatigue life and safety of welded joints contaning surface cracks

摘要

摘要: 本研究以对接接头焊趾表面裂纹疲劳扩展随机模型与统计分析为基础,分析了焊趾表面裂纹疲劳扩展的极限状态,探讨了带表面裂纹焊接构件疲劳扩展寿命与安全性的概率评定方法。

Abstract: Based on the analysis and stochastic model for surface crack growth at weld toe, the limit state of the surface crack growth was discussed. A probabilistic method of assessing the fatigue life and safety of welded joints containing surface cracks is presented.
