▎ 摘　　要

In this research, thermal buckling of trapezoidally corrugated functionally graded graphene platelet reinforced composite (FG-GPLRC) laminated panels are considered and analyzed. Each layer of trapezoidally corrugated panels (TCPs) are reinforced with different value of graphene platelets (GPLs) leading to a piecewise functionally graded (FG) media. The elastic properties of the laminated TCP are evaluated using the Halpin-Tsai scheme. The TCP is modeled by multiple patches. The stability equation of each patch is established using a logarithmic higher order shear deformation theory (HSDT) and then incorporating the isogeometric method. The associated matrices are then transformed appropriately to the global coordinates. Also, the continuity requirements between the boundaries of the patches are satisfied by the bending strip method (BSM). The reliability and accuracy of the proposed method are ascertained through comparison of the computed results with those exist in the open literature as well as those generated by ABAQUS. Afterwards comprehensive parametric studies are provided to show the effects of all influencing factors on the thermal buckling behavior of trapezoidally corrugated FGGPLRC laminated panels. It is found that with constant corrugation angle and amplitude, when more corrugation units are added to the original panel, the critical buckling temperature difference remains almost constant.
