Prediction of Fatigue Life of Welded Joints Made of Fine-Grained Martensite-Bainitic S960QL Steel and Determination of Crack Origins
Figure 6
The pictures of fatigue fractures have been observed during fractographic investigation. Samples of weldments made of S960QL steel tested under the total strain amplitude εa = 0.2%: (a) I-shaped and (b) V-shaped welds.
