A theoretical model for calculating the modal density and mode counts of sandwich panels with composite face sheets in thermal environments is presented. Governing equations are derived by applying the Hamilton’s principle based on an improved ordinary sandwich panel theory. Modal density and mode counts are calculated using the wavenumber space integration with simply supported and clamped boundary...
Modal density of sandwich panels with composite face sheets and orthotropic core is presented based on an improved ordinary sandwich panel theory. The governing equations are derived by applying the Hamilton’s principle, where in-plane rigidity of the core is considered and the material and reference axes are not limited to be identical to each other. Modal density is obtained using wavenumber space...
