CONCERNING THE STRESSED STATE OF A MULTIPLY CONNECTED PLATE WITH A REINFORCED EDGE

The article deals with a two-dimensional problem in elasticity theory concerning the biaxial extension of an infinite plate with four pairwise identical apertures, which have a common axis of symmetry and a common center of symmetry. The edges of the apertures, which have the form of an ellipse or a regular curvilinear polygon, are reinforced apertures in the case of extension along or apparatus of analytical functions, the problem is reduced to two infinite systems of linear equations for the coefficients of the expansions of the desired complex potentials. These systems are solved by the method of truncation for the special case of a plate with four reinforced apartures in the case of extension along or across the line of centers. Graphs and tables of the stresses as functions of the height of the reinforcing rings are constructed. Also presented are results of experiments on determination of the stress-concentration coefficients in a plate of finite dimensions (with two circular and two square reinforced apertures), depending upon the ratio of the characteristic aperture size to the width of the plate.
