Effects of Material Parameters on Longitudinal Vibration Band Gaps in Thin Phononic Crystal Plates

Abstract:

The improved plane wave expansion method is used to investigate the effects of material parameters on the longitudinal vibration band gaps in thin phononic crystal plates. Both square lattice and graphite lattice are considered. Results show that the parameters playing the essential roles are the mass density ratio and the Young modulus ratio of the scatterers and the host materials.
