Elastic-plastic behaviour of pipe bends with in-plane bending

Abstract

The theory for the in-plane and out-of-plane bending of a curved pipe is reviewed by considering it as an extension of the theory for symmetrically loaded shells of revolution. This treatment is adopted with the intention of modifying an existing elastic-plastic programme for shells of revolution so that it can perform the analysis of pipe bends with in-plane bending. Results are presented for elastic and elastic-plastic behaviour of pipe bends with in-plane bending. These results agree with theoretical and experimental results found in the literature.
