چکیده
Abstract The adequate modeling of the micro/nano arc resonators' dynamics is vital for their successful implementation. Here, a size-dependent model, wherein material structure, porosity, and micro-rotation effects grains are considered, derived by combining couple stress theory, multi-phase classical Euler–Bernoulli beam aiming to characterize frequency tunability resonators as monitoring either axial load or electrostatic force first time. dimensions optimized show various phenomena in same arc, namely snap-through, crossing, veering. three natural frequencies monitored, showing size dependency on tuning, snap-through/back, pull-in instability shrinking scale from micro- nano-scale. Significant changes static snap-through voltages resonance were shown shrinks. A dynamic analysis resonator's vibration shows dramatic effect size-dependency around veering zone.

Nonlinear Dynamics of Nanomechanical Resonators
In the last decade we have witnessed exciting technological advances in the fabrication and control of microelectromechanical and nanoelectromechanical systems (MEMS&NEMS) [16, 19, 26, 54, 55]. Such systems are being developed for a host of nanotechnological applications, such as highly sensitive mass [25, 34, 67], spin [56], and charge detectors [17, 18], as well as for basic research in the m...
متن کاملFinite Element Modeling of Strain Rate and Grain Size Dependency in Nanocrystalline Materials
Nanocrystalline materials show a higher strain-rate sensitivity in contrast to the conventional coarse-grained materials and a different grain size dependency. To explain these phenomenon, a finite element model is constructed that considers both grain interior and grain boundary deformation of nanocrystalline materials. The model consist of several crystalline cores with different orientations...
