N2 - This paper investigates the static and dynamic electromechanical response of 1-3 piezocomposites through numerical and experimental characterizations. First, we examine the nonlinear electromechanical response of 1-3 piezoelectric/polymer composites. The piezocomposites contain square or circular piezoelectric rods in an epoxy matrix. Experiments are conducted to measure the displacement versus electric field curves, using the device specimen of the 1-3 piezocomposites. Three-dimensional finite element analysis is also carried out to study the nonlinear electromechanical fields in the 1-3 piezocomposites by introducing a model for polarization switching. Comparison is then made between simulation and experiment. Next, we examine the dynamic response of 1-3 piezoelectric/polymer composites under AC electric fields. The impedance/phase angle and dynamic electromechanical fields in the 1-3 piezocomposites are discussed in detail.
