Abstract: Based on the classical laminated plate theory, a finite composite laminated plate with an elliptical hole is treated as an anisotropic multiple connected plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, an analytical solution concerned with the stress concentration around an elliptical hole in a finite composite laminated plate is obtained with the help of the Faber series expansion and the least square boundary collocation technique. The effects of hole sizes, layups and loading conditions on stress concentration are studied in detail.

Key words: laminates, stress concentration, holes(mechanics)
