The macroscopic properties of the P1type MFC (Macro Fiber Composite) actuator are analyzed by using the homogenization model based on the plane stress hypothesis and the twodimensional periodical displacement field assumption. The applicability of the model to the static deformation analysis of the MFC cantilever beam is studied. The ANSYS simulation results show that the model is suitable for analyzing the static deformation of MFC cantilever beam. Compared with the nonhomogenization model, the relative error of the cantilever beam deflection is less than 5.77%, and the influence of the e32 component of the piezoelectric stress matrix on the deflection of the beam (e32 effect) is the secondary factor in the homogenization model. On the basis of adopting the homogenization model, when the e32 effect is further ignored, the relative error of the deflection of the beam does not exceed 1.36% compared with the original homogenization model.
