Stress Concentration of Shoulder Fillets in a Round Test Specimen under Torsion : Stress Concentration of Shoulder Fillets in a Plate under Anti-Plane Shear

摘要

This paper deals with the stress concentration analysis of shoulder fillets in a round test specimen under torsion and in a flat plate under anti-plane shear. The stress fields induced by the ring force acting to the tangential direction in the infinite body and the anti-plane shear force in the infinite plate are used as fundamental solutions to solve those problems. The stress concentration factors are systematically calculated under verious geometrical conditions. Through the comparision of the present results with the previous research works, it is found that the results of Matthews-Hooke and of Tsuji et al. are in good agreement with the present results. The stress concentration factors are illustrated in tables and diagrams so they can be used easily in design or research.
