Abstract
Effects of various methods of notch preparation on the notched slow bend fracture strengths of heat-treated alloy steel specimens were studied. The results indicate that several kinds of cracks result in about 35 per cent lower strength than a machined 0.005 in. root radius notch. The importance of testing sufficiently large size specimens to reveal this difference is shown.
