AbstractIn this work, a novel approach for optimization of finite element modeling (FEM) of lossy piezoelectric elements has been proposed. Procedure of optimization has consisted in sequential and iterative application of FEM and piezoelectric resonance analysis to complex electric impedance spectra of piezoceramic elements. For validation of proposed optimization procedure, FEM calculations of standard shape piezoelements (disks, shear plates, bars, and rods) made from porous PZT-type piezoceramics were fulfilled using FEM ANSYS software package
