Abstract: In this study, stress concentration factors (SCF, Kt) of rectangular plate with multiple opposite semicircular notches are considered under uniform tensile stress so as to analyze the notch deformation due to the effect of stretching of plate. The maximum stress in the notched plate is found to determine the stress concentration factor. A plate with multiple notches under the axial load creates stress concentration near the notch and it is much larger than the average stress on the plate. Both analytical and finite element methods are used to calculate the maximum stress around the notch. SolidWorks Simulation 2014 has been employed for modelling and static analysis of linear elastic isotropic rectangular plate of size 700 x 400 x 20 mm. The uniform tensile load of pressure with a magnitude of 75 Mpa is applied on both sides of rectangular plate normal to the sides of notches with three different notch radius to plate width ratio (2r/D) = 0.2 , 0.3 and 0.4, corresponding notch radius to center distance (2r/L) = 0.4, 0.6 and 0.8. The result obtained on both analytical and finite element methods are compared and the percentage of error has been evaluated.
