Estimation of Stress Concentration Factor for a plate with hole under Axial Tension Loading

The purpose of this study is to investigate the effects hole/holes on stress concentrations in a plate using current industry standard software - Finite Element Analysis (FEA). Plate with common engineering application such as automobile, marine, aerospace and mechanical structures. Hole/Holes can be seen many thin-walled automobile structures components. For example, are found residential/commercial buildings’ steel structural studs allow plumbing installation, web or flange box girders bridges furnished holes ease inspection works, electrical heating conduits walls ceilings ribs attached main spar an aeroplane’s wing frequently come holes. These one type discontinuities within structure (e.g. thin plate) that leads changes elastic stiffness may tend failures. Proper knowledge stresses, strains, deflection concentration (SC) required design any In geometry plate, under different loading, rises from abrupt change. And due this, throughout cross-section, uniform distribution does not occur. At point concentration, results failures like fatigue cracking plastic deformation commonly Hence, it very important know about plates present circular central hole offset subjected uniaxial loading (axial tension) calculated Equations SCF given by Peterson dependent three parameters namely, radius (a), distance bottom edge centre (c) top (e). By varying either ‘c’ ‘e’ ratio ‘e/c’, effort made factors for determination effect distance. show von Mises stresses increased increasing ‘e/c’ ‘a/c’, which turn increases finally failure.
