The stress concentration of In718 superalloy after friction welding and compare with Mar-M247 and In718 welded joints
Friction stir welding (FSW) is a new method that the joining is carried out by friction between two metals and heat creation. The stress concentration phenomena in welded joint cause the stress increasing in welded zone. In this research, modeling and analysis of similar junction of IN718 and Mar-M247 and non-similar junction of IN718-Mar-M247 superalloys were performed by ANSYS Software and fi...

متن کاملAn Experimental Investigation of Stress Concentration Factor
In this project, investigation of stress concentration factor is carried out. Some specimens with edge notches, multiple edge notches, and holes are fabricated. While two specimens are hand sawed to produce edge cracks. The stress concentration factor (K) value is compared between the theoretical values found in standard K value chart with our experimental results. Effect of multiple notches is...
متن کاملStress 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 کاملEstimating the fatigue stress concentration factor of machined surfaces
In this study the effects of surface texture on the fatigue life of a high-strength low-alloy steel were evaluated in terms of the apparent fatigue stress concentration. An abrasive waterjet was used to machine uniaxial dogbone fatigue specimens with specific surface quality from a rolled sheet of AISI 4130 CR steel. The surface texture resulting from machining was characterized using contact p...
