Abstract

The analysis of composite rectangular sandwich plates composed of an orthotropic core and composite laminated faces is presented for bending and free vibration. A method of solution based upon the Ritz method is used. A displacement field which includes transverse shear deformation of the face layer is applied to the honeycomb sandwich plate. The effect of transverse shear deformation on the center deflection and natural frequencies is studied, and the applicability of the displacement field is discussed. Also, the effects of fiber angle on the face layer, core thickness and transverse shear modulus of the core on natural frequencies of the honeycomb sandwich plate are discussed.
