Torsional stresses the transverse fillet weld tubular joints

Abstract

Torsional stresses, Tr6 and tei, in the transverse fillet tubular weld joint subjected to torsional load have been analyzed by the finite element method using triangular and quadrilateral izoparametric arisymmetric fourier type torus finite elements. There is an »»symmetry with respect to geometry and material properties but no arisymmetry with respect to the loading. With respect to material properties, two kinds of joints are considered in the study. One consists of steel tubes and steel weld material, the other steel tubes and brass weld material. All of the materials used are assumed linear-elastic. Changing the torsional stresses, along the weld legs and the weld throat, are plotted in dhnensionless coordinates.
