Thermal Buckling of Simply Supported Piezoelectric FGM Cylindrical Shells

A Closed-Form Solution for Thermal Buckling of Piezoelectric FGM Hybrid Cylindrical Shells with Temperature Dependent Properties

“…Shen [8,9] studied the mechanical postbuckling analysis of piezoelectric FGM hybrid cylindrical shells, using a singular perturbation technique. Also Mirzavand and Eslami [10] presented the buckling analysis of simply supported FGM cylindrical shells with piezoelectric actuators under thermal loads. Dynamic thermal buckling of suddenly heated FGM cylindrical shells under combined axial compression and external pressure is investigated by Shariyat [11] using the finite element method, while the temperature dependency of FGM properties is considered.…”

Active Control of Thermal Buckling of Shells of Revolution Using Piezoelectric Patches

“…In Figure 5, a comparison between the results generated for cylindrical shells to Downloaded by [University of Windsor] at 18:08 19 November 2014 embedded piezoelectric layers and voltage equals +200 V with Ref. [17] is made. The actuator layer thickness is 0.001 m. The Young's modulus, Poisson's ratio and the coefficient of thermal expansion are for zirconia: 151 GPa, 0.3, 10 −5 1/ C, respectively.…”

“…For thin shells, the linear temperature assumption may be justified. In this paper, UTD is compared with LTD, as it has been previously done by many researchers [17,18,22,23].…”

“…In determining critical buckling temperature, the effects of shear deformation are taken into account. Material properties are independent of temperature, which in Downloaded by [University of Windsor] at 18:08 19 November 2014 linear buckling analysis is a prevalent hypothesis [17,18,22,23]. Both uniform temperature distribution (UTD) and linear temperature distribution (LTD) through the thickness are studied.…”

“…Mirzavand and Eslami [17] presents thermal buckling analysis of FGM cylindrical shells which are integrated with surface-bonded piezoelectric actuators and are subjected to the combined action of thermal load and constant applied actuator voltage. Derivation of the equations is based on the higher-order shear deformation shell theory, using the Sanders nonlinear kinematic relations.…”
