Abstract : An analytical solution is presented for the stresses around two interacting circular openings of equal size in a thin elastic plate of isotropic material under biaxial loads. The openings can be either unreinforced or reinforced. The reinforcing material which is the same as that of the parent plate is assumed to be concentrated around the boundaries of the openings. The stresses are obtained in bipolar coordinates as infinite series. Numerical convergence of these series is governed by the ratio of the size and spacing of the two openings. The results are obtained on the IBM 7090 computer as stress concentration factors for a number of hole geometries and reinforcements which frequently occur in practice. (Author)
