Abstract
An analytical procedure for the determination of stress concentrations and strength pre diction of finite composite laminates with elliptical holes is proposed. The Airy stress function expressed in terms of full Laurent's series and a complex variable technique in conjunction with the least-squares "boundary collocation method" are employed in this study. Laminate strength is predicted by using the concept of characteristic curve and the Yamada-Sun failure criterion. Numerical solutions for various hole sizes, layups, material properties, and loading conditions are shown in graphical form and comparisons are made with some other available results.
