Nonlinear response and buckling analysis of eccentrically stiffened FGM toroidal shell segments in thermal environment

Aerospace Science and Technology, 2018
Abstract This paper presents an analytical approach to study nonlinear response and buckling analysis of FGM toroidal shell segments reinforced by FGM stiffeners surrounded by elastic foundations in thermal environment and under external pressure. The formulations are based on Reddy's third-order shear deformation shell theory (TSDT) with von Karman ...

Buckling Analysis of Eccentrically Stiffened Functionally Graded Toroidal Shell Segments under Mechanical Load

Journal of Engineering Mechanics - ASCE, 2016
AbstractAn analytical approach is presented to investigate the linear buckling of eccentrically stiffened functionally graded thin toroidal shell segments subjected to axial compression, lateral pressure, and hydrostatic pressure. On the basis of classical thin shell theory, the smeared stiffener technique and the adjacent equilibrium criterion, the ...

Nonlinear buckling responses of radially pressured FG-GPLRC toroidal shell segments

Journal of Science and Transport Technology, 2023
An analytical approach for nonlinear buckling of functionally graded graphene platelet reinforced composite toroidal shell segments is presented in this paper. The Ritz energy procedure is executed, and radial pressure–deflection expression is constituted to obtain the postbuckling strength and critical buckling pressure of the shells.

Electro-Mechanical Buckling of Shallow Segments of Functionally Graded Porous Toroidal Shell Covered by Piezoelectric Actuators

International Journal of Structural Stability and Dynamics, 2023
The current work deals with the mechanical buckling behavior of saturated porous toroidal shell segments sandwiched by piezoelectric actuator layers. Material properties of the porous shells with nonuniform distributed porosities are assumed to vary as a specific function of the thickness and porosity parameters.
