Abstract

In this study, to examine the effect of different parameters on stress analysis of Infinite plates with central Quasi-square cutout using Imperialist competitive algorithm and also to introduce general optimum parameters in order to achieve the minimum amount of stress concentration around this type of cutout on orthotropic plates are purposed. Basis of the presented method is expansion of analytical method conducted by Lekhnitskii for circular and elliptical cutouts. Design variables in this study include fiber angle, load angle, curvature radius of the corner of the cutout, rotation angle of the cutout and at last material of the plate. Imperialist competitive algorithm is the mathematical model and the computer simulation of human social evolution. Finite element numerical solution is employed to examine the results of present Analytical solution. Overlap of the results of the two methods confirms the validity of the presented solution. Results ae showed that by selecting the aforementioned parameters properly, less amounts of stress could be achieved around the cutout leading to an increase in load-bearing capacity of the structure.
