Postbuckling of FGM rings

International Journal of Mechanical Sciences, 2014
Abstract Buckling and post-buckling behaviors of a moderately thick closed ring made of a through-the-thickness functionally graded material (FGM) is investigated in this research. It is assumed that material properties of the ring are distributed across the thickness in terms of a power law model.

Thermal postbuckling behavior of CNT-reinforced composite sandwich plate models resting on elastic foundations with tangentially restrained edges and temperature-dependent properties

Journal of Thermoplastic Composite Materials, 2020
Buckling and postbuckling behaviors of sandwich plates reinforced by single-walled carbon nanotube (CNT), rested on elastic foundations and subjected to uniform temperature rise, are investigated in this article. CNT is embedded into matrix phase through

Postbuckling Analysis of Composite Laminated Panels

AIAA Journal, 2000
A description is given of the development of a spline e nite strip method for predicting the response of composite laminated, prismatic panels to a progressive uniform end shortening. The response is assumed to be geometrically nonlinear, with the nonlinearity introduced in enhanced strain ‐displacement equations in a total Langrangian approach.

POSTBUCKLING OF LAMINATED COMPOSITES WITH DELAMINATIONS

34th Structures, Structural Dynamics and Materials Conference, 1993
Summary: Postbuckling analysis of laminated composites with delaminations is presented. A finite element method based on a layerwise laminated composite plate theory is developed to formulate and solve the problem. Geometric nonlinearity in the sense of von Kármán and imperfections in the form of initial global deflection and initial delamination ...

Postbuckling Analysis of Flexible Elastic Frames

Journal of Applied and Industrial Mathematics, 2018
completely geometrically nonlinear beam model based on the hypothesis of plane sections and expressed in terms of engineering strains and apparent stresses is applied to the structural analysis of frames. The numerical results are obtained by the Raley–Ritz method with a representation of solutions as a sum of analytical basis functions which were ...

An enhanced reduced-order model based optimization method for buckling and postbuckling performances of variable stiffness composite plates

Mechanics of Advanced Materials and Structures, 2021
The great potential of variable stiffness laminates in maximizing buckling load is obvious over straight fiber laminates, however the optimum design of such VAT laminates which has much more design variables and larger computational efforts, is still a ...

Boundary layer modeling of surface residual tension in postbuckling behavior of axially loaded silicon panels at nanoscale embedded in elastic foundations

Mechanics based design of structures and machines, 2020
Here, nonlinear buckling and postbuckling properties of cylindrical silicon nanopanels of finite length resting on elastic foundation exposed to axial compression have been studied by taking into account surface free energy (SFE) effect.

Postbuckling of tapered plates

International Journal of Mechanical Sciences, 1969
Abstract A general method of analysing the postbuckling of variable-thickness plates with edges restrained against lateral expansion is described. Since the deflexions are often greater than the plate thickness the large deflexion equations apply and these are solved using the dynamic relaxation method. After comparing the results with an alternative
