Thermal post-buckling analysis of functionally graded material structures using a modified FSDT

摘要: Abstract The thermal post-buckling responses of Functionally Graded Material shell structures are reported in this paper. Geometrically nonlinear analysis based on a modified First order Shear Deformation Theory proposed. theory takes into account the shear strains with parabolic shape function and it verifies zero stresses condition at top bottom surfaces. For numerical computation, four nodes elements implemented. large displacement is described by Green–Lagrange strains. Moreover, assumed that exposed to uniform, linear temperature distributions through thickness direction. mechanical properties according power law distribution either temperature-independent or temperature-dependent material considered. Two examples functionally graded plates cylindrical shells presented highlight effectiveness accuracy present finite element procedure. effect geometrical parameters, volume fraction index boundary conditions performed.
