Computation for the torsion of a thick-walled tube with fillets using tapered section assumption

摘要

This paper presents, in terms of the tapered section assumption, an effective method for calculating local stress and elastoplastic load of a thick-walled tube with fillets under torsion. The relationships of the stress concentration factor with fillet depth t, radius p of the fillet and the internal radius r of the tube are discussed. The elastoplastic limit loads and local stress analysis are given. The computed results are compared with previous works. This shows that the expressions obtained in this paper are indeed effective, simple and easy to apply in engineering.
