...Lingling Chen; Xinyu Xing; Chuo Zhao; Shengyou Yang Flexoelectricity exists in all inhomogeneously deformed dielectric materials and is of great interest in engineering science, especially in microelectromechanical systems. However, the flexoelectricity is relatively small compared to the commonly...

... flexoelectric fields. In contrast to classical crack–inclusion problems, the interactions between these flexoelectric fields may locally change the electromechanical behaviors of materials and result in some interesting phenomena. To better understand the crack–inclusion interactions in flexoelectric solids...

...Xinpeng Tian; Mengkang Xu; Haiyang Zhou; Qian Deng; Qun Li; Jan Sladek; Vladimir Sladek Due to the stress concentration near crack tips, strong flexoelectric effect would be observed there, which might lead to new applications of flexoelectricity in material science and devices. However, different...
