The flexoelectric effect is a coupling of polarization and strain gradient, which exists in a wide variety of materials and may lead to strong size-dependent properties at the nanoscale. Based on an extension to the classical beam model, this paper investigates the electromechanical coupling response of piezoelectric nanobeams with different electrical boundary conditions including the effect o...

Flexoelectricity is an electromechanical coupling between the electric field and mechanical strain gradient, as well strains observed in all dielectric materials, including those with centrosymmetry. demands C1-continuity for straightforward numerical implementation governing equations gradient theory are fourth-order partial differential equations. In this work, alternative collocation-based m...

Non-conductive materials like rubbers, plastics, ceramics, and even semiconductors have the property of flexoelectricity, which means that they can generate electricity when bent twisted. However, an irregular shape or a peculiar load has been necessary condition to realize weight deformability specific ratios flexoelectricity solids are limited. In this work, we develop theoretical model three...

A finite element model is proposed permitting prediction of elastic wave bandgaps periodic composite microplates incorporating flexoelectric effect. In this model, we applied curvature-based flexoelectricity and Mindlin plate theories derived a formulation that has been implemented for bandgap analysis. The utilizes three-node triangle with 30 degrees freedom satisfying kinematics assumptions. ...
