Abstract

This work presents a numerical simulation using MEF submodelingscheme to study overall response of a tubular welded T supported at itsprincipal ends and subjected to a load at its free end. This welded jointhas a semi-elliptical crack at the toe of the weld in the saddle region.The response of the welded joint has been evaluated according to themeasurement displacement line of the applied load at the free end, thestrain field around the weld and the crack opening displacement. Tovalidate the obtained results, these were compared with experimentaldata available in the literature.
