Electrical fatigue response for ferroelectric ceramics under electrical cyclic load

Fatigue crack growth in ferroelectrics under electrical loading

“…the cycle dependence of remanent polarization, strain hysteresis, coercive field and dielectric constant of ferroelectric ceramics upon electrical fatiguing. [18][19][20][21][22][23][24][25][26] In contrast, the present experimental study is concerned with the distinct phenomenon of fatigue cracking-the nucleation and growth of cracks or microcrack damage due to cyclic electrical loading. * Corresponding author.…”

Phase fragility and mechatronic reliability for Pb(Mg1/3Nb2/3)O3–PbTiO3 ferroelectric single crystals — A review

“…The electrical degradation of ferroelectrics, by shrinking the remnant polarization and expanding the coercive field of the hysteresis loop, is a serious concern in application. [23][24][25][26][27][28] In the mechanical sense, ferroelectric materials are fragile, with fracture toughness typically in the order of 1 MPa ffiffiffiffi m p . That weakness often leads to fracture under an intensive electric field, and the fatigue crack propagation under an alternating electric field.…”

Effect of microstructure on lifetime performance of barium titanate ceramics under DC electric field loading

“…A considerable literature currently exists concerning the reliability and fatigue behaviors of ferroelectric ceramics under alternating current (AC) electric fields. [4][5][6][7][8][9][10][11][12] Additionally, a recent study by the authors shows * Corresponding author. Tel.…”
