Abstract : A general method is presented for determining the stresses around two openings of any shape in a large plate of elastic isotropic material. The two openings can have individual boundary reinforcements. The method is based on the complex variable approach combined with the Schwarz successive approximation technique. As an illustration of the method, the stresses are computed for the case of a small circular opening near a large circular opening. The amounts of reinforcing material on these two openings were varied to determine the optimum reinforcement. Several cases which frequently occur in ship construction are included. (Author)
