Abstract

This chapter provides a comprehensive free vibration and thermal stability analyses of sandwich structures. The analyses are carried out by virtue of advanced and refined variable-kinematic structural models based on the method of power series expansion of displacement components. In particular, in the first part of the chapter classical sandwich structures made up of anisotropic or orthotropic face sheets and honeycomb or foam core are analyzed. The second part is devoted to the investigation of functionally graded material (FGM) sandwich structures. Two different typologies have been taken into account: (1) sandwich structures with FGM core and (2) sandwich structures with FGM face sheets. In this latter case, various configurations, to determine the best FGM sandwich structures in terms of stability characteristics, are also thoroughly examined.
