Abstract: The nonlinear electromechanical behaviors of a cracked ferroelectric single crystal subjected to pure electrical loadings are investigated with different crack face electrical boundary conditions by a three-dimensional phase field model. Phase field simulations show that the crack face electrical boundary condition has significant influence on the electrical and mechanical responses of the ferroelectric single crystal to an external electric field. The coercive field for the polarization switching of the singl…
