Abstract

Many cases of rolling contact fatigue failure, such as those that occur in railway rails, rolling bearings, and gears, are due to repeated high shear load. In order to prevent such fatigue failures, the resistance of a material against to repeated high shear load must be determined. The fatigue crack growth rate is dependent on the stress intensity factor range of Mode II ΔK II. However, Mode II crack propagation characteristics vary according to the method by which they are determined. We improved the experimental method proposed by Murakami and measured the effective stress intensity factor range of Mode II AK IIeff. Changes to the jigs and specimen were made and the experimental method was such that the ideal mechanical model was expected to be approached. Furthermore, to measure the ΔKIIeff, several strain gauges were applied to the specimen around the crack tip. Using the improved method, some ΔK IIeff values during the Mode II fatigue crack propagation tests can be measured.
