ABSTRACT

Parametric changes in material properties of a sandwich plate with honeycomb core for studies of stiffness, mass, and damping characteristics can be performed by analytical methods at a low computational cost. This chapter investigates the influence of honeycomb core on modal responses of a sandwich plate having honeycomb as a core material. In this study, carbon fiber has been used for the face sheet, and aluminum honeycomb material has been used as the core of the sandwich plate. The finite element method with simply supported boundary conditions has been used to carry out the modal analyses. The geometry of the sandwich plate has been modeled in Ansys using APDL code. The analysis is based on first-order shear deformation theory (FSDT). Initially, the validation with available results is compared for the values of the natural frequency of the sandwich plate. Further various examples have been carried out to study the influence of parameters such as cell size, face sheet thickness, and core thickness on the natural frequencies.
