通过实验和数值模拟相结合的方法研究了外加电压对多层压电致动器电极前电弹性场集中的影响。进行了实验，以测量在各种电负载条件下的内部和表面电极附近的应变。采用有限元法求解了电弹性耦合边值问题。计算了应变、应力和电位移集中，讨论了局域极化反转引起的非线性行为。并将模拟结果与实验结果进行了比较。
The effects of applied voltage on the electroelastic field concentrations ahead of electrodes in multilayer piezoelectric actuators were examined in a combined experimental and numerical investigation. Experiments were performed to measure the strain near internal and surface electrodes at various electrical loading conditions. The finite element method was also used to solve the coupled electro-elastic boundary value problem. The strain, stress and electric displacement concentrations were calculated and a non-linear behavior induced by localized polarization switching was discussed. A comparison of strain concentration was made between experiment and simulation.
