Crack appearance 1.2 mm from the crack initiation site
The regions shown in Fig. 8 and 9 consist mostly of poorly
formed dimples with blunt edges; these might be interpreted as
dimple rupture caused by overload if they were not part of the
sequence of images that clearly shows the crack began as fatigue..
Sometimes a crack comprises mostly one type of surface, such as the
poorly formed dimples shown in Fig. 8 .

This technical brief is intended to warn failure analysts against assuming that dimples indicate overload fracture. Dimples simply mean that microvoid processes were active; these processes can occur in cyclic as well as monotonic fractures. The failure analyst must examine the entire fracture, the macroscopic as well as the microscopic features, to be confident of the cracking mode.
