In this paper we propose an analytical method for determining the behavior of symmetric laminates containing a rectangular or a square hole. This method is based on the theory developed by Savin [G.N. Savin, Stress concentration around holes, Pergamon Press, New York, 1961], for an elliptical hole, and uses the parametric representation of a given rectangle. The results obtained by this method are compared with those obtained by finite elements. This method allows the better understanding of the behavior of composite plates under inplane loading for different types of loading, different side ratios, different fillet radii, and different types of materials.
Key words: composite materials / symmetric laminate / stress concentration factor / rectangular hole / square hole
