A stress analysis method has been developed for a biaxially loaded fastener hole in a laminated plate of finite geometry. The method is based on a variational formulation involving complex variables. In this method, the equilibrium and compatibility equations are satisfied in the domain of the plate due to the employment of the complex stress potentials and all the boundary conditions are satisfied through a variational statement. Therefore, the requirement for finite width corrections in relatively large fastener hole cases is avoided. The method has been verified through comparison with finite element results.
