Stress Concentration of Circumferential Notch by FEA

Engineers develop the engineering components for different application. Most of the engineering components contain geometrical discontinuities, such as slots and grooves. Generally grooves in termed of notches use in shaft or bar. These geometrical irregularities play important role in the stress-strain concentration generated in notch area. The stress increases above the certain limit then material gets failure. Hence, knowledge of stress-concentration on the engineering components is very important for design and application of various engineering elements. In addition to knowledge of total deformation in components at various loading condition is very important. That is the study of stress-concentration and total deformation in notch bar at axial loading is necessary. There are very few attempts has been made to investigate stress concentration in double circumferential notch bar effect for various type of loading condition. In this studied investigation for Square, U-shape and V-shape double circumferential notch bar, under the axial load and found stress concentration and total deformation of notch bar by using analytical, finite element analysis and experimental analysis.
