FATIGUE CRACK PROPAGATION IN WELD METAL AND HAZ

In a dynamically loaded structure fatigue is a critical problem when the structure contains welded joints, because a weld represents a major stress concentration , in the form of a change of section, together with weld defects. The result is that the fatigue cracks initiate more rapidly in welded than in nonwelded structures, and consequently the major part of the fatigue life is spent propagating a crack. Thus the subject of fatigue crack propagation, which is currently receiving a great deal of attention, is of particular interest in the context of fatigue in welded structures.
