Abstract

Abstract:

The gradient metallic cellular material has gradient pore structures from one surface of the material to the other one resulting in varying material properties,such as mass density and elastic modulus. The vibration response of sandwich panels may be influenced when the traditional homogeneous cellular core is replaced by gradient metallic cellular core. Based on the high-order plate theory and considering the coupling effect between the density and the elastic module of gradient metallic cellular materials, the vibration equation for the sandwich panel with composite face sheet and gradient metallic cellular core is developed. The influence of three gradient types of cores (unidirectional distribution, positive gradient symmetrical distribution and negative gradient symmetrical distribution) on the natural frequency of sandwich panels is discussed. The vibration responses of sandwich panels with three gradient metallic cellular cores under the same impulsive loading are discussed.

Key words: gradient metallic cellular material, sandwich panel, high-order plate theory, vibration response, impulse load
