Vibration and buckling analysis of FG-CNTRPC micro plates subjected to electro-magnetic field using refined zigzag theory

Nonlocal vibration and buckling of carbon nanotube reinforced composite (CNTRC) micro plate bounded with piezoelectric sensor and actuator orthotropic layers are investigated in this article. In order to model the sandwich plate refined zigzag theory (RZT) is applied. Distribution of single-walled carbon nanotubes (SWCNTs) along the thickness direction of the CNTRC micro plate are assumed as uniform distribution (UD) according to the rule of mixture .The functionally graded (FG) CNTRC micro plate subjected to electro-magnetic fields is surrounded with viscoWinkler foundation. Equations of motion obtain by Hamilton s principle. In order to calculate frequency and buckling load of sandwich plate, an exact solution is employed. The effects of some significant parameters such as volume fraction of CNTs, magnetic field, length of system, and viscoWinkler foundation on the vibration and buckling loud of system are investigated. The results depict that the properties of CNTRC micro plate improved by reinforcing plate whit more CNTs. In addition, electromagnetic fields are considerable parameters to control the behavior of FGCNTRC micro plate. It is hoped that the results of this study could be applied in design of nano/micro mechanical sensor and actuator systems.
