Thermo-mechanical analysis of porous functionally graded graphene reinforced cylindrical panels using an improved third order shear deformable model

In this paper, a novel shear deformable model is developed to investigate the temperature -dependent thermo-mechanical responses of porous functionally graded graphene rein-forced composite (FG-GPLRC) cylindrical panels subjected to an initial blast pressure. An improved third order shear deformation theory, which has more rigorous kinematic of dis-placement, is implemented in the construction of the proposed model. Then, the current model is used to predict the thermo-mechanical responses of the nanocomposite panels made of metal foams reinforced by graphene platelets (GPLs). Lagrange equations are used to derive the governing equations corresponding to thermal buckling as well as the free and forced vibrations of the porous FG-GPLRC cylindrical panels. A Navier-type solution, which is free from computational errors, is implemented. Validation works demonstrate that the present model provides accurate predictions of mechanical responses for compos-ite structures. A comprehensive parameter study is carried out to explore the influences of several key parameters regarding the thermo-mechanical behaviors of the porous FG-GPLRC cylindrical panels.& COPY; 2023 Elsevier Inc.
