In this study, the free and forced vibrations of a delaminated beam-plate resting on a two-parameter (Pasternak type) elastic foundation are investigated. We consider a homogeneous isotropic clamped beam-plate compressed axially and subject to an external time dependent force. In order to study the vibration of the delaminated beam-plate relative to a post-buckled state we should solve the static deformations. This has been accomplished by the successive substitution method.The free and forced vibration analysis are then performed. Results are represented in both graphical and tabulated forms and shows that the natural frequencies are affected by the change in the delamination length, depth and location and also affected by the change in the elastic foundation parameters.
