Abstract:
For further knowledge of fatigue behaviour of materials and welded joints under combined stress fatigue, fatigue testing equipment was necessary to develop. The desired
equipment could apply cyclic torque and bending deflections to the test specimen. It could allow independent and easy adjustment of mean and amplitude values of each type
of deflection. Mechanism was capable of providing adjustable phase shift between torque and bending cycles. Arrangements were provided for measurement of angle of twist
and deflection. Shot peening was found to be benefitial even under combined bending and torsional fatigue. The improvement in fatigue life was up to 100%
