Nanocantilevers have become key components of nanomechanical sensors that exploit changes in their resonant frequencies or static deflection in response to the environment. It is necessary that they can operate at a given, but adjustable, resonant frequency and/or static deflection ranges. Here we propose a new class of nanocantilevers with a significantly tunable spectrum of the resonant frequ...

This research deals with the nonlinear material and geometric behaviors of reinforced concrete deep beams resting on linear or nonlinear Winkler foundation. The finite elements through ANSYS (Release-11, 2007) computer software are used. The reinforced concrete deep beam is modeled using (SOLID 65) 8 node brick element and the soil is modeled using linear spring (COMBIN 14) element or nonlinear...
