چکیده انگلیسی
An ultrathin film is flexible but tends to buckle when subjected to compression and temperature variation. The buckling behavior will adversely affect its mechanical performance, therefore, it should be accurately evaluated and under controlled. Accordingly, it is vital to study thermal buckling behavior of ultrathin films. In the present work, thermal buckling of bilayer graphene sheets (GSs) embedded in Pasternak-type foundations is studied based on the nonlocal elastic theory and classical plate theory (CLPT). We have examined three types of thermal distribution, namely linear, nonlinear and uniform temperature distributions through the thickness of GSs. The effects of boundary condition, aspect ratio, nonlocal parameter, elastic foundation parameter, geometric size, stacking types on the critical buckling temperature loads are investigated.
