Abstract

The determination of elastic, dielectric and piezoelectric homogenised constants of piezocomposite materials is required for the optimisation and the performance evaluation of the material. This paper presents an inverse method enabling the determination of the effective electro-acoustic tensor |C, e, ε|. Data are displacement field measurements. The model used for the forward problem is presented. The calibration of the inversion process is carried out. A piezocomposite plate device is fully characterized. The determined parameters from the inverse problem are validated using other data, the acoustic transmission coefficient of the plate.
