Stress analysis of finite composite laminate with multiple loaded holes

Based on the classical laminated plate theory\ a _nite composite plate weakened by multiple elliptical holes 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 study concerned with the stress distributions around multiple loaded holes in _nite composite laminated plates subjected to arbitrary loads was performed[ The analysis makes use of the Faber series expansion\ conformal mapping and the least squares boundary collocation techniques[ The e}ects of plate and hole sizes\ layups\ the relative distance between holes\ the total number of holes and their locations on the stress distribution are studied in detail[ Some conclusions are drawn[
