In many ferroelectrics, large electromechanical strains are observed near regions of composition- or temperature- driven phase coexistence. Phenomenologically, this is attributed to easy re-orientation of the polarization vector and/or phase transiti

The strain response of a polarised PZT was characterised using Digital Image Correlation (DIC). The DIC algorithm is based on a global approach and regularises the displacement field using the balance equations of solid mechanics. The measurement err

International audience; The anhysteretic behavior of a soft Pb(Zr,Ti)O3 was measured from 25 °C to 175 °C. The experimental determination of the anhysteretic polarization curve, combined with classical P-E and S-E loop measurements, allows for an e
