摘要：
The effect of changing temperature on the damping properties of free vibrations of sandwich cylindrical panels is studied in this paper. It is assumed that the material properties of the facings and core of the sandwich panel studied change with temperature. The effects of the viscoelastic damping of the core layer and geometrical non-linearities of the vibrating panel have been included in this study. Dissipated energy is used to investigate the damping. It is found that the rapidly changing temperature strongly affects the vibration responses and damping properties of the cylindrical sandwich panels.
