摘要：

Electrical boundary conditions influence the nonlinear electromechanical behavior of ferroelectric materials. In this study, a hard and a soft PZT are tested under tensile loading in short and open circuit. Depolarization of the specimen or evolution of the electric field due to the piezoelectric effect is recorded. Nonlinear stress-strain curves are greatly affected by the electric field which appears in open circuit and reduces ferroelastic domain switching. (C) 2003 Elsevier B.V. All rights reserved.
