Buckling Analysis for a Ring-Stiffened FGM Cylindrical Shell Under Hydrostatic Pressure and Thermal Loads

Abstract

This paper studies the buckling analysis for a ring-stiffened cylindrical shell consisted of functionally graded material (FGM) subjected to hydrostatic pressure and thermal loads. Material properties of the ring-stiffened FGM cylindrical shell are assumed to be temperature-dependent, and vary smoothly through the thickness direction of the structure according to a volume exponent. Based on the Donnell assumptions, buckling loads of the ring-stiffened FGM cylindrical shell are presented by utilizing the Galerkin method. Numerical results reveal that thermal loads, volume exponent and geometric parameters have significant effects on the buckling behavior of the ring-stiffened cylindrical shell.

Thermotropic yield characteristic of the ceramic–alloy composite beam induced by a unilateral heat source

“…Mirzavand and Eslami [32,33] gave the solution for thermal buckling of piezoelectric functionally graded cylindrical shell considering the temperature dependent properties of material. For the shell structure, Dai et al [34] analyzed and discussed the buckling behavior of the stiffened functionally graded cylindrical shell under the mechanical and thermal loads. The thermal post-buckling of functionally graded cylindrical shell with temperature-dependent properties was studied by Shen [35], and he also studied the post-buckling behavior of functionally graded plate [36].…”

Buckling of Annular Plate Joint With Circular Beam

“…In the case of this typical buckling the rings may be considered as circular beams. Almost in all studies of ring-stiffened shells the beam model of the ring is used (see [1]- [3] and references there).…”

On the solution of the buckling problem of functionally graded truncated conical shells with mixed boundary conditions

“…Dai et al. [42] studied buckling analysis for a ring-stiffened FGM cylindrical shell under hydrostatic pressure and thermal loads using Donnell theory and Galerkin method. Sun et al [43] presented buckling of functionally graded cylindrical shells under combined thermal and compressive loads.…”
