Abstract

This work presents a numerical simulation using MEF submodeling
scheme to study overall response of a tubular welded T supported at its
principal ends and subjected to a load at its free end. This welded joint
has 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 the
measurement displacement line of the applied load at the free end, the
strain field around the weld and the crack opening displacement. To
validate the obtained results, these were compared with experimental
data available in the literature.
