WAVE PROPAGATION IN ONE-DIMENSIONAL PERIODIC CEMENT-BASED PIEZOELECTRIC COMPOSITE LAYERED STRUCTURES USING FEM
In this paper,cement-based piezoelectric composite material is introduced into the periodic structure,and a new one-dimensional phononic crystal structure with air gap is proposed.The finite element method is used to calculate the band structure,and the influencing factors of the band gap are discussed in detail.From the results,we can find that the introduction of air gap can effectively reduce the starting frequency and increase the width of band gap.The position of the air gap and the geometric parameters of the periodic structure have important influences on the band gaps.The solving method and the related conclusions can be useful for vibration and noise reduction in practical engineering.
