摘要:
Fatigue crack growth in headed stud and welding seam under I-II mixed loading are experimentally investigated. The modified CTS specimens are abstracted both from the headed stud and the welding seam. The influences of I-II mixed loading angle and ratio on fatigue crack growth are investigated and clarified. The correlation of the fatigue crack growth rate (FCGR) data with different formulas of equivalent SIF range are discussed and the intrinsic parameters of FCGR under I-II mixed loading are recommended. Results show that the fatigue crack ex...
