- Abstract
Optimal hydrophone performance for 1-3 piezoelectric composites is achieved from the design of material properties. The piezocomposite consists of piezoceramic rods immersed in a polymer matrix. We obtain the effective moduli of the piezocomposite by the differential effective medium theory and the results are explicitly dependent on volume fractions of the piezoceramic rods and elastic properties of the matrix. Topology optimization with level set method is used to optimize the elastic properties of the matrix phase. Numerical examples propose three-dimensional microstructures with negative Poisson’s ratio for the polymer matrix that can enhance hydrostatic charge coefficients of the piezocomposite.
