In the present paper, higher-order shear deformation theory is utilized to study the buckling behavior of annular graphene sheets in the thermal environment. The novelty of the present paper is that buckling of an annular graphene sheet in the thermal environment is developed. To obtain the governing equations, Hamilton's principle is utilized and solved numerically using the differential quadrature method. Further, Winkler and Pasternak's foundation is developed to consider the elastic medium. To examine the accuracy and efficiency of the present model, the paper's results are compared with the articles available in the literature. Results of the current research indicate that for a particular value of the Pasternak coefficient, the critical buckling temperature increases as the parameter of the internal to external radius ratio decreases.
