dc.description.abstract[EN] The Finite Element Analysis (FEA) is used in this work to study the impedance curves and modes of motion at resonance of non-standard shear plates, thickness poled and longitudinally excited. An ecological, lead-free, piezoelectric ceramic of (1-x)(Bi0.5Na0.5)TiO3–xBaTiO3 with x=0.06 (BNBT6) composition is studied. The FEA modeling is based on the full matrix of the material coefficients. These are obtained from complex impedance measurements on two thickness poled resonators. A study as a function of the variations of the dimensions of the plate was accomplished (t=thickness for poling, and L, w=lateral dimensions, where w is the distance between electrodes for the electrical excitation). We aimed to a further understanding, and, thus, ability to control, the coupling of the main shear resonance and the lateral modes. The use of uncoupled shear modes to obtain the material parameters is a key issue for their determination as complex quantities, thus considering all material losses, electromechanical, dielectric and elastic.es_ES
