Abstract

Consider a sandwich plate with anisotropic composite laminated faces and an ideally-orthotropic honeycomb core. In this paper, a one-dimensional model for the free vibration analysis of a plate with an across the width delamination located at the interface between the upper face and core is proposed. With this model the natural frequencies and mode shapes of the delaminated composite sandwich beams can be found by solving the eigenvalues and eigenvectors of twelve simultaneous linear homogeneous algebraic equations. For the purpose of verification, the solutions are reduced to the case of delaminated composite beams by letting the terms containing the core properties vanish, which show that our results match well with the experimental results done by other researchers.
