摘要：

The paper presents a nonlinear static research for an electrically actuated piezoelectric laminated micro- beam. On the basis of the Euler- Bernoulli hypothesis, and the responses under electric force [a purely direct current (DC)] are investigated. By using the Taylor series expansion, a set of governing equations of nonlinear integro-differential type is derived. Then using the Galerkin method, an analytical is presented. Numerical examples show, when a purely DC is applied, there exist an instantaneous pull-in voltage, the effect of the pull-in phenomenon have the relation not with elastic parameter but with voltage on the piezoelectric layer.
