Abstract
We discuss the effective (apparent) stiffness of a nano-or microsized thin-walled structure consisting of two elastic flexible faces and a capillary fluid between them. We take into account capillary forces acting on a free surface of the fluid. These capillary effects play a significant role at the micro- and nanoscales and influence mechanical properties of such structures. We introduce the effective stiffness parameters of a considered three-layered plate as functions depending on the elastic properties of faces as well as the surface tension
