Frequency response of a two-dimensional trusslike periodic panel

The frequency response of a two-dimensional trusslike periodic panel is studied adopting the transfer matrix of a repeated cell. Intracell resonance occurs at relatively low frequencies, causing high modal density of the panel. Effects of panel curvature, sag of cell diagonal member, mass added by a liquid filling the cell cavity, and damping by constrained viscoelastic layers are studied parametrically.
