采用半逆解法，本系列工作中研究了功能材料悬臂梁力-电耦合问题的几个基本解，考虑了梯度效应对基本解的影响。本文是该系列工作的第一部分，研究了悬臂梁梁端受力偶作用的情况。
These series works are concentrated on finding the general solutions in smart materials and structures. In order to find the solutions of a piezoelectric cantilever beam under different kinds of load conditions, the semi-inverse method is used. As the first part of all, the present paper deals with a piezoelectric cantilever beam subjected to a couple of forces. Some important parameters of the electro-mechanical fields are obtained and discussed. Several distribution curves such as stress and electric potential for material PZT (i.e. Pb(Ti0.48Zr0.52)O3) are given. It should be pointed out that the material is functionally gradient in density.
