A comparison of buckling and postbuckling behavior of FGM plates with piezoelectric fiber reinforced composite actuators

摘要: Abstract Compressive postbuckling under thermal environments and due to a uniform temperature rise are presented for simply supported, shear deformable functionally graded plate with piezoelectric fiber reinforced composite (PFRC) actuators. The material properties of materials (FGMs) assumed be in the thickness direction according simple power law distribution terms volume fractions constituents, both FGM PFRC layers temperature-dependent. governing equations based on higher order deformation theory that includes thermo-piezoelectric effects. initial geometric imperfection is taken into account. A two step perturbation technique employed determine buckling loads (temperature) equilibrium paths. numerical illustrations concern compressive behaviors perfect imperfect, geometrically mid-plane symmetric plates fully covered or embedded actuators different sets electric loading conditions. results monolithic actuator, which special case present study, compared those reveal that, case, applied voltage usually has small effect load–deflection curves actuators, whereas more pronounced same
