Comparison the stresses and deflections of an isotropic and orthotropic rectangular plates with central circular hole under tension load

The distributions of stresses and deflection in rectangular isotropic and orthotropic plates with central circular hole under transverse static loading have been studied using finite element method. The object of this present work is to analyze the effect of D/Y ratio (where D is hole diameter and Y is plate width) upon stress distribution and deflection in plates under tension subjected to a static loading. The D/Y ratio is varied from (0.1) to (0.9). The results are obtained for four different boundary conditions. The variations of stresses and deflections with respect to D/Y ratio are presented in graphical form. The finite element formulation is carried out by using the analysis section of the ANSYS package
