Thermal buckling and postbuckling behavior of FG-GRC laminated cylindrical shells with temperature-dependent material properties

摘要: Thermal postbuckling analysis is presented for graphene-reinforced composite (GRC) laminated cylindrical shells under a uniform temperature field. The GRC layers are arranged in functionally graded (FG) graphene reinforcement pattern by varying the volume fraction each layer. GRCs possess dependent and anisotropic material properties extended Halpin–Tsai model employed to evaluate properties. governing equations based on higher order shear deformation shell theory include von Karman-type kinematic nonlinearity thermal effects. A singular perturbation method conjunction with two-step approach applied determine equilibrium path or without geometric imperfection. An iterative scheme developed obtain numerical buckling temperatures load–deflection curves shells. results reveal that FG-X piece-wise FG distribution can enhance capacity of when subjected loading.
