The paper investigates equilibrium problems for an elastic plate containing a thin rigid inclusion in the case of free edge. The inclusion may be delaminated from the elastic plate thus forming an interfacial crack. The considered boundary conditions lead to non-coercive boundary value problems. The cases of possible fixing of the plate at one or two given points are analyzed. Necessary and sufficient conditions for the existence of solutions to the problems under consideration are found.
