CONCERNING THE EQUILIBRIUM OF A PLATE WITH ARBITRARILY SITUATED REINFORCED CIRCULAR APERTURES

The article deals with the two-dimensional stressed state of an infinite isotropic plate with any number of arbitrarily situated circular openings, the edges of which are reinforced by narrow elastic rings. The boundary conditions are written down with use of the complex Kolsov-Muskhelishvili potentials. By means of the series method in combination with the method of Cauchy-type integrals, the problem is reduced to an infinite quasi-irregular system of equations, which is realized on a digital electronic computer by the truncation method. The numerical data of some calculations are presented, which make it possible to ascertain the influence of the number of apertures on the stressed state of the plate.
