Torsional stresses in the transverse fillet weld tubular joints

Torsional stresses, 'tre and tel , in tbe transverse fillet tubular weld joint subjected to torsional load have been analyzed by the finite element method using triangular and quadrilateral izoparametric axisymmetric fourier type torus finite elements. There is an axisymmetry with respect to geometry and material properties but no axisymmetry 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 dimensionless coordinates.
