Stress Concentration Factors in Spherical Vessels with Single Oblique Nozzle
Finite element method is employed to analyze the spherical vessel intersected by an oblique cylindrical nozzle. In this survey the stress and strain distributions on acute and obtuse sides of the connection under internal pressure are studied widely although axial and moment loadings on the nozzle are also studied briefly. Stress concentration factors for a wide range of geometrical ratios in t...
متن کاملGeneralized Stress Concentration Factors for Equilibrated Forces and Stresses
As a sequel to a recent work we consider the generalized stress concentration factor, a purely geometric property of a body that for the various loadings, indicates the ratio between the maximum of the optimal stress and maximum of the loading fields. The optimal stress concentration factor pertains to a stress field that satisfies the principle of virtual work and for which the stress concentr...
متن کاملStress concentration factors for multiplanar joints in RHS
Hollow sections are most suitable for welded connections between members. The welding procedure is fairly straightforward in RHS, because they do not require profiling which is necessary for circular hollow sections. Although many multiplanar and uniplanar joints in structures are present, limited evidence is available for the fatigue behaviour of joints made of rectangular hollow sections. Thi...
متن کاملThe Weld Profile Effect on Stress Concentration Factors in Weldments
The assessment of beneficial effects of weld geometry modification methods is considered in this paper. Since all these methods significantly increaese weld toe radius, its influence on stress concentration factors is analised. The dependance of theoretical stress concentration factors vs. weld toe radius was determined by using both finite element analisys and photoelasicity method for various...
متن کاملDetermination of Stress Concentration Factors of a Steam Turbine Rotor by FEA
Stress Concentration Factors are significant in machine design as it gives rise to localized stress when any change in the design of surface or abrupt change in the cross section occurs. Almost all machine components and structural members contain some form of geometrical or microstructural discontinuities. These discontinuities are very dangerous and lead to failure. So, it is very much essent...
