Nonlinear Dynamic Response Analysis of Carbon Fiber Reinforced Polymer Enhanced with Carbon Nanotubes on Elastic Foundations in Thermal Environments

plates enhanced with carbon nanotubes resting on elastic foundations in thermal environments using the finite element method is investigated. The effective material properties of the multiscale composite are calculated using Halpin–Tsai equations and fiber micromechanics in the hierarchy. Three types of distribution of temperature through the thickness of the plate namely, uniform, linear, and nonlinear are considered. The governing equations are derived based on Inverse Hyperbolic Shear Deformation Theory and von Kármán geometrical nonlinearity. Five types of impulsive loads namely the step, sudden, triangular, half-sine, and exponential pulses are considered. Numerical results reveal that the deflections of multi-phase composites significantly decrease with a small percentage of carbon nanotubes. Also, it is found that in thermal nvironment, central deflection of the plate was reduced using a maximum of 1% of the carbon nanotube in polymer composites and adding higher weight percentage showed no significant change in the peaks of central deflection.
