摘要：

In the present study, the influence of structural damping on impulse response of sandwich plates with FG-porous graphene reinforced core is investigated. The sandwich plate contains Aluminium face sheets and a core which is made up of functionally graded (FG) porous graphene nanoplatelets (GNP) reinforced material. The pores are created throughout the core along the thickness direction by employing certain functions. The homogenized properties such as elastic modulus and density are obtained using Halpin-Tsai model and rule of mixture, respectively. The governing equations based on higher-order shear deformation theory (HSDT) are developed using variational principle. The finite element method along with Newmark's integration technique is employed to investigate the impulse response of the sandwich plates. The influence of damping, porosity, GNP weight fraction, etc. is discussed.
