Stress Concentration Factor for a Flat Plate with Fillets and Notches under Axial Load Using ANSYS® Software

Abstract

This paper analyzes the stress concentration factor in a flat plate with two fillets and two notches under an axial load. The maximum stress in the fillets and the notches are calculated using the ANSYS® software. These maximum stresses are used to determine the stress concentration factor in the notches and the fillets for the relations W/w = 1.2, 1.5, 2.0, 2.5, 3.0 in terms of the ratio r/L. The stress concentration factors obtained are plotted as a function of the ratio r/L.The results show that for the notches the r/Lratio does not have much effect on the stress concentration factor. Meanwhile, in fillets the stress concentration factor decreases as the ratio r/L increases. Finally, the least squares method is used to determine sixth grade polynomial equations that can be used to determine the stress concentration factor at the fillet of the plate under study.
