Finite Element Analysis and Fatigue Life Estimation of Plate with Different Stress Levels

Abstract

A number of analytical and numerical techniques are available for the two dimensional study of stress concentration around the hole(s) and notches in isotropic and orthotropic plates subjected to in-plane or transverse loading conditions. The influence of the structural dimension D/A (where D is hole diameter and A is plate width) ratio upon stress concentration factor for different cases is studied in the present work but plate with center hole is created and adjacent small holes created but diameter is varied and distance between one hole to another is also varied so finally study the stress concentration around the holes using ANSYS software. work is to investigates how part geometry can influence the maximum stress found at critical points for a rectangular plate with a large hole in the center and changing the adjacent small hole diameters to see the effects on the magnitude of the maximum stress and understand how this influences the stress concentration factor. The symmetry of this condition will be used to make the analysis simpler by dividing the part into quarters and finally estimating the fatigue life of the plate with varied parameters.
