Abstract

The paper offers an analytical solution of the problem of the stressed state of an infinite plate with a circular opening reinforced with a concentric round cover plate. The cover plate is assumed to be elastically attached to the main plate along its perimeter. The structure is loaded at infinity with uniform tension. The solution is obtained by expanding the components of the stress-strain state into a Fourier series about the angle coordinate. After satisfying the edge conditions, the solution retains only the first series terms. The model problem is solved. The cover plate was shown to reduce the stresses near the opening. The solution was verified by comparing computational results with calculations performed using the finite element method. The model suggested is highly accurate. A parametric study was performed to examine the impact of cover plate thickness and plate thickness ratios, and cover plate radius and opening radius ratios on the stress in the most loaded section.
