Stresses and electric fields induced in the poling processes of both polycrystalline and single crystal thick
walled cylinders are investigated and compared using a finite element analysis together with a micromechanical
ferroelectric constitutive law. The analysis reveals that the polarization process begins at the
inner diameter and spreads outward through the cylinder as the applied electric potential is increased. The
piezoelectric strain and the remnant strain produce strain fields that are not compatible with the geometry.
In the single crystal material the poling is not uniform. It is affected by the angle between the crystal
orientation and the electric field direction.
