Abstract
Nondestructive measurements of residual stresses were successfully attempted by the acoustoelastic technique on butt-welded joints of a piping carbon steel plate. Usefulness of the technique considering the effect of material anisotropy is emphasized. Based on the measured residual stresses, the prediction of the fatigue crack growth was done using the superposition technique. It is shown that results agree well with experiments. The effect of experimental accuracy on life prediction is also included.
