چکیده

In the present manuscript, the buckling behaviors of carbon fiber reinforced polymer (CFRP) plates will be probed for the first time. The coupled influences of existence of symmetrically and asymmetrically distributed pores in the media and implementation of graphene platelets (GPLs) as the coating of the CFs on the mechanical responses of the system will be covered, too. The GPL coatings will construct a GPLs-reinforced interphase which helps the structure to tolerate greater buckling loads. The effective stiffness of the system will be enriched utilizing a micromechanical procedure regarding for the influence of available porosities in the material. Afterward, the principle of virtual work will be used for the goal of deriving the governing equations of the plate-type structure based upon the expansion of the displacement field of a refined-type higher-order shear deformation theory (HSDT). At the end, the buckling load of the system will be obtained solving the eigenvalue buckling problem within the framework of the Navier’s well-known analytical solution for the case of which all of the edges are simply supported. The validity of the proposed investigation is examined and a mentionable agreement between the results of this work and those available in the open literature is observed. The generated results indicate on the crucial role of the GPLs-reinforced interphase on the stability endurance of the CFRP plate.
