Abstract
In this study, the stress distributions in adhesive butt joints of cylindrical pressure vessels are analyzed by the finite element method using eight-node-quadrilateral axisymmetric finite elements. The structure consists of two cylindrical adherends bonded by an adhesive arid the joint is subjected to [...] Read more.
In this study, the stress distributions in adhesive butt joints of cylindrical pressure vessels are analyzed by the finite element method using eight-node-quadrilateral axisymmetric finite elements. The structure consists of two cylindrical adherends bonded by an adhesive arid the joint is subjected to an internal pressure. Stress distributions and the effects of the adhesive thickness on the stress distributions in the joint are studied. Full article

Abstract
The effects of addendum modification coefficient on the root stresses of spur gear are investigated. By considering positive and negative addendum modificated gears, distributions of root stresses are determined by the finite element method. The root stresses of addendum modificated gears are compared [...] Read more.
The effects of addendum modification coefficient on the root stresses of spur gear are investigated. By considering positive and negative addendum modificated gears, distributions of root stresses are determined by the finite element method. The root stresses of addendum modificated gears are compared with those of standard gears. The problem is analyzed as one in the plane stress and, also the plane strain. Full article

Abstract
Torsional stresses, τ and τθz, in the 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 [...] Read more.
Torsional stresses, τ and τθz, in the 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. Full article
