چکیده انگلیسی
This paper presents an advanced piezo-material characterization method to obtain intensive elastic parameters of the k33 vibration mode from the k31 geometry through crystallographic approach with canted polarization. Three effective k31 bars with 0, γ, and Ï/2-γ degree angled polarization is needed where 0 < γ < Ï/4. Eliminating s13E,* and s55E,* components from the effective elastic parameters, the k33 mode elastic parameters could be derived. Pb{(Zr0.56Ti0.44)0.99Nb0.01}O3 with 0, 15, 30, 45, 60, 75 ° angled polarization were prepared and characterized under constant vibration velocity to obtain the effective elastic parameters for the k31 mode. The intensive elastic compliance s33E and elastic loss tanÏâ²33 are derived and compared to the measured value from the conventional methods Due to the low structural impedance of the measured geometry (i.e., large sample capacitance), the reliability on the proposed method is extraordinary, and the implicit relative error in the conventional methods could be avoided.
