Vibration analysis of delaminated composite plates under axial load

The vibration analysis of a delaminated composite plate subjected to the axial load was performed. The concept of continuous analysis was used to model the delaminated composite plate as a plate on a discontinuous elastic foundation. The elastic adhesive layer between the buckled composite plate and the undeformed substructure working as a foundation to the plate is represented by linear parallel springs. In general, this model can be used to obtain vibration solutions of the delaminated composite plate with general boundary conditions, delaminations with multiple number, and various delamination shapes, sizes and locations. The proposed approach is extremely simple, efficient, and accurate, and quite important and useful for various applications.
