讨论了带裂纹矩形压电材料在低温机电载荷作用下的I型能量释放速率。在与电极方向垂直或平行的方向上产生裂纹，并在电极方向平行或垂直的方向上施加电场。通过平面应变有限元分析，讨论了电场和局域极化开关对低温下压电陶瓷能量释放率的影响。
We discuss the mode I energy release rate of a rectangular piezoelectric material with a crack under electromechanical loading at cryogenic temperatures. A crack was created normal or parallel to the poling direction, and electric fields were applied parallel or normal to the poling. A plane strain finite element analysis was carried out, and the effects of electric field and localized polarization switching on the energy release rate were discussed for the piezoelectric ceramics at cryogenic temperatures.
