Effect of Crack-Tip Morphology on Cleavage-Crack Extension



Values of fracture toughness obtained by cleavage reinitition of arrested cleavage cracks in compact specimens are found to agree with those obtained from thermal shock experiments on much larger cylinders. In contrast, toughness values obtained using fatigue-precracked compact specimens are somewhat higher. It is suggested that the arrested cleavage crack tip is a more potent flaw than the fatigue precrack.
