▎ 摘　　要

In this paper, large deflection behavior of a bilayer graphene sheet (BLGS) is investigated under uniformly transverse load in thermal environment with various boundary conditions. Using the principle of virtual work, the non-linear formulations are derived based on first-order shear deformation plate theory (FSDT) and large deflection von Karman equations that includes the thermal effects. Differential quadrature (DQ) method and the Newton-Raphson iterative technique is employed to solve the system of nonlinear algebraic equations. To study the effect of elastic foundation on the results, two types of embedded in polymer matrix (EIPM) and resting on polymer matrix (ROPM) are considered. Besides, the influences of temperature rise, material properties, boundary conditions, small scale effect, thickness-to-length ratio, aspect ratio and polymer matrix properties are studied in detail.
