摘要：
Based on the classical composite laminate theory, the bending problem of a finite composite plate weakened by multiple elliptical holes is studied by means of the complex variable method. The present work is intended to express the complex potentials in the form of Faber series aided by the use of the least squares boundary collocation techniques on the finite boundaries. As a result, concise and high accuracy solutions are presented for the stress distribution around the holes. Finally, numerical examples are presented to discuss the effects of some parameters on the stress concentration around the holes.
