We present a new approach based on coupling the extended finite element method (XFEM) and level sets to study surface and interface effects on the mechanical behavior of nanostructures. The coupled XFEM-level set approach enables a continuum solution to nanomechanical boundary value problems in which discontinuities in both strain and displacement due to surfaces and interfaces are easily handl...
This article investigates the size dependent on piezoelectrically layered perforated nanobeams embedded in an elastic foundation considering material Poisson’s ratio and flexoelectricity effects. The composite beam is composed of a regularly squared cut-out core with two piezoelectric face sheet layers. An analytical geometrical model adopted to obtain equivalent variables core. To capture effe...
