Prediction of fatigue crack growth rate in welding residual stress field
TLDR
In this paper, the effect of residual stresses on fatigue crack growth is investigated by paying attention to a fatigue crack that initiates at the weld metal and propagates perpendicular to the weld line, and the experimental results indicate that the crack growth rates are equivalent by use of the effective stress intensity range, based on the measurements of crack opening ratio.About:
