Flexoelectric Fracture-Ratchet Effect in Ferroelectrics [PDF]
Physical Review Letters, 2019 The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate that, in piezoelectric materials, a consequence of flexoelectricity is that crack propagation is helped or hindered depending on whether it is parallel or antiparallel to the ...
