Abstract
This paper is devoted to illustrate the thermal buckling response of a graphene platelets (GPLs)-reinforced nanoplate with porosities lying on Pasternak’s foundation. The porous nanocomposite plate is exposed to 2D magnetic field and humid environment. In accordance with a nonlinear distribution law, the porosities and GPLs weight fraction are presumed to be varied through the nanoplate thickness. The modified Reddy’s plate theory containing the thickness stretching effect is employed with the nonlocal strain gradient theory to deduce the governing equations from the principle of virtual displacement. These equations are solved utilizing Navier type solution to obtain the critical buckling temperature. To check the accuracy of the present analysis, the deduced buckling temperature is compared with that published in the literature. Additional parametric studies are introduced to investigate the impacts of humidity, magnetic field, porosity factor, GPLs weight fraction and foundation stiffnesses on the critical buckling temperature of the FG GPLs nanoplates.
