...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...

...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...
