Název v původním jazyce

Software for modeling of acoustic properties of piezoelectric composites

Popis výsledku v původním jazyce

The software developed under the systém Matlab is intended for modelling of the acoustic properties of the strongly heterogeneous piezoelectric materials with periodic structure. It serves especially for prediction of the frequency band gaps. The imput data involve a microstructural geometry of the reference cell in 2D and material properties of all components. Computing is based on the finite element method and on the eigenvalue problem solution. As the output the homogenized mass tensor is obtained and other homogenized material oefficients are evaluated, comprising elasticity, dielectricity and the piezoelectric coupling. For selected frequency ranges the strong and weak band gap distribution is analyzed. The software was employed as a tool of the basic research in the field of the strongly heterogeneous media modellig.
