Flutter of composite plates with elastic supports

This study aims at flutter characteristics of orthotropic plates subjected to supersonic flow. The plate is subjected to uniform in-plane forces(N x, Ny) and its edges are assumed to be elastically restrained(with various degree) against rotation. This type of boundary conditions covered a wide range of B.C's from simply support to clamped supports. The analytical solution is obtained using classical plate theory. Frequency equations of these systems are very large and difficult to solve. A simple method of solving this type of equations has been used in order to investigate the flutter characteristics of orthotropic plates. The effect of plate geometry, material properties, in-plane load and boundary condition are presented and discussed.
