Abstract

Abstract

The flexoelectric fields’ interactions between microholes of common defects in solid materials are studied. With the collocation mixed finite element method, the distributions of the stress, the strain gradient, and the flexoelectric field around the hole of the single hole and the double holes, respectively, are compared. The numerical simulation results indicate that, the flexoelectric fields’ interaction around the double holes emerges with the gradual decrease of the distance between the double holes. In addition, the effects of the distance between holes and the size of holes on the flexoelectric fields’ interaction between microholes are explored. The results show that, reducing the distance between double holes and shrinking the size of holes will induce to an enhanced interaction of the flexoelectric field between double holes.
