Abstract : For a homogeneous, transversely isotropic, second-order piezoelectric and infinitesimally prebent, prepolarized and prestretched prismatic bar, we find second-order Saint-Venant solutions. It is found that the electric field alone does not introduce any bending in the second-order piezoelectric bar. However, the electric field induced by the bending of the bar can be used to ascertain the magnitude and direction of the bending vector. The curvature of the centroidal axis of the bar can be changed by the simultaneous application of the electric field and the bending moment.
