Postbuckling of sandwich plates with FGM face sheets and temperature-dependent properties

摘要: Abstract Compressive postbuckling under thermal environments and due to heat conduction are presented for a simply supported, sandwich plate with FGM face sheets. The material properties of sheets assumed be graded in the thickness direction according simple power law distribution terms volume fractions constituents, both homogeneous substrate temperature-dependent. governing equations based on higher order shear deformation theory that includes effects. initial geometric imperfection is taken into account. A two-step perturbation technique employed determine buckling loads (temperature) equilibrium paths. numerical illustrations concern compressive behavior perfect imperfect, different environmental conditions. results reveal temperature changes, fraction sheets, substrate-to-face sheet ratio have significant effect load plates. also confirm case conduction, path no longer bifurcation type.
