Photos taken instantaneously of Load, Position (LLD), CMOD parameters and Both Crack Tips at maximum load point of a typical monotonic fracture test 4.1. Monotonic Fracture Testing The typical images of a crack tip of a 12-inch pipe tested are shown in Fig. 5 (c) and Fig. 5(d). Fig. 5(c) shows the opening of the hair line crack already present due to fatigue pre-cracking. It should be noted that this straight opening of the hairline crack should not be considered crack growth due to loading. Fig.5 (d) show the further crack growth (c) Image of Crack Tip A (d) Image of Crack Tip B g. 7.
