摘要：A number of analytical and numerical techniques are available for the two dimensional study of stressconcentration around the hole(s) and notches in isotropic and orthotropic plates subjected to in-plane or transverseloading conditions. The influence of the structural dimension D/A (where D is hole diameter and A is plate width) ratioupon stress concentration factor for different cases is studied in the present work. Peculiarity in Stress concentrationfactor for different stresses like x, y, xy, von and deflection for different materials is observed. Stress concentrationfactor for all stresses shows marked mitigation upon introduction of auxiliary holes. Finite element method has beenadopted for analysis and the results have been presented in graphical forms with discussion. The finite elementformulation and its analysis are carried out using ANSYS package. This research work can provide structure engineersa simple and efficient way to estimate the effect of SCF and its mitigation in plate structures made of isotropic andorthotropic materials.
