Stress-Strain State of Bent Plate with System of Cracks with Faces Contacting Within Constant-Height Zone

The bending problem for a circular plate weakened by a system of through straight cracks has been solved under assumption that the crack faces contact within a zone of constant height. Using the complex potentials for the plane problem and the classical plate bending problem, the solution of the problem has been reduced to a series of linear conjugation problems. The system of singular integral equations on the crack faces has been obtained. The boundary conditions of the circular plate have been satisfied analytically. The contact force between the crack faces and the moment and stress intensity factors have been numerically analyzed at various parameters, with the corresponding dependences constructed.
