SCF On Isotropic Rectangular Plate With Central Circular Hole Using Finite Element Analysis

The present work is the study of effect of stretching of an isotropic rectangular plate with centrally located circular hole under uniform tensile load. A loaded plate with the presence of hole creates stress concentration near the hole which is much larger than the average stress on the plate. The stress concentration factor has been calculated by using both analytical and finite element methods. Solidworks simulation is used for modeling and static analysis of linear elastic isotropic plate of size 500 x 300 x 25 mm, made up of AISI 4340 steel. The uniform tensile load of magnitude of 50 Mpa is applied on two opposite sides of rectangular steel plate with three different hole to width ratio of 0.2, 0.4 and 0.6 and the error percentage for finding SCF between analytical and finite element method are 4.8 %, 2.9 % and 4.7 % respectively.
