Random vibration analysis of thick rectangular nanocomposite cross-ply laminated plates

Random vibration of a symmetric cross-ply thick rectangular laminated plate reinforced by single-walled carbon nanotubes subjected to a stationary random field pressure is studied. First order shear deformation theory is imposed to consider the thick plate. An analytical solution according to the appropriate boundary conditions is presented to solve the derived formulation. Numerical results are compared with available experimental data and the other theoretical models which show good agreement. Parametric study including the effects of CNT volume fraction and width to thickness ratio of the plate on the mean square of plate deflection is carried out gives reasonable outcomes. The results show that increasing in both of the correlation decaying parameter and width to thickness of the plate and also decreasing the CNTs volume fraction leads to the more mean square of plate deflection.
