...Jinchen Xie; Christian Linder The flexoelectric effect, characterized by the induction of electric polarization by strain gradients, exhibits a remarkable size dependence. This makes flexoelectricity highly relevant for nanoscale electromechanical systems. Inevitably, flexoelectric solids, like all...

...Jinchen Xie; Christian Linder Flexoelectricity, a remarkable size-dependent effect, means that strain gradients can give rise to electric polarization. This effect is particularly pronounced near defects within flexoelectric solids, where large strain gradients exist. A thorough understanding...

... 2012 The theoretical investigation of the size dependent behavior of a Bernoulli–Euler dielectric nanobeam based on the strain gradient elasticity theory is presented in this paper. The variational principle is utilized to derive the governing equations and boundary conditions, in which...

...Jia Li In this paper, we present a new model to predict the fracture in brittle materials from a geometrical weakness presenting an arbitrary stress concentration. The main idea is to combine the strain gradient elasticity with a cohesive model that includes both the displacement and the rotation...
