Thermal buckling and postbuckling of functionally graded graphene-reinforced composite laminated plates resting on elastic foundations
AbstractThis paper presents the modeling and analysis for the thermal postbuckling of graphene-reinforced composite laminated plates resting on an elastic foundation and subjected to in-plane temperature variation. A micromechanical model is used to estimate the temperature-dependent material properties of the graphene-reinforced composites (GRCs). Piece-wise functionally graded (FG) GRC layers along the thickness direction of a plate is considered in this study. Employing the higher order shear deformation plate theory, the governing equations for FG-GRC plates are derived and the effects of plate-foundation interaction and temperature variation are included in the modeling. A two-step perturbation technique is applied to obtain the buckling temperature and the thermal postbuckling load-deflection curves for perfect and imperfect FG-GRC laminated plates. The results show that the buckling temperature as well as thermal postbuckling strength of the plates can be increased as a result of the functionally graded graphene reinforcement for the plates.
HighlightsThe concept of functionally graded materials is extended to the GRC laminated plates.A multi-scale approach for thermal buckling analysis of FG-GRC laminated plates is proposed.The temperature-dependent material properties are taken into account.FG reinforcement has a significant effect on the thermal postbuckling of GRC laminated plates.
