Experimental Investigation on Very High Cycle Fatigue Behavior of Welded Joint
焊接接头超高周疲劳实验研究

Three groups of welded joints,including circular butt welded joint without and with shot peening treatment and cross-plate welded joint,were adopted and their very high cycle fatigue behavior study was carried out by using ultrasonic fatigue testing technique in ambient air and at room temperature with a stress ratio R=-1.Experimental results show that fatigue strength of circular butt welded joint is much higher than that of cross-plate welded joint,and the fatigue strength of welded joint is improved by s...
