This paper describes a special hybrid finite element to represent a loaded hole in a sheet. The shape functions of the element satisfy stress equilibrium and strain compatibility throughout the element, and the applied loading boundary conditions. The applied loading is represented by a finite Fourier series, and the coefficients of the element shape functions are matched with the Fourier coefficients. A computer program has been written to generate the element stiffness and stress recovery matrices. The program also produces equivalent nodal forces and initial stresses related to the applied loading. Accurate results have been obtained from several example analyses. Author
