Thermal postbuckling analysis of FG-CNTRC doubly curved panels with elastically restrained edges using Reddy's higher order shear deformation theory

Vietnam Journal of Mechanics, 2020
For the first time, postbuckling behavior of thick doubly curved panels made of carbon nanotube reinforced composite (CNTRC), under preexisting external pressure and subjected to uniform temperature rise is analyzed in this paper. Carbon nanotubes (CNTs)

Effects of constraint curvature on structural instability: tensile buckling and multiple bifurcations

, 2012
Bifurcation of an elastic structure crucially depends on the curvature of the constraints against which the ends of the structure are prescribed to move, an effect which deserves more attention than it has received so far.

Design and Control of a Dual‐Coil Magnetic Guidewire for Smooth and Adaptive Curvature Steering in Vascular Intervention

SmartBot, Volume 2, Issue 1, March 2026.
Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Hilltop buckling as the A and O in sensitivity analysis of the initial postbuckling behavior of elastic structures

Journal of Civil Engineering and Management, 2009
The coincidence of a bifurcation point with a snap‐through point is called hilltop buckling. In this paper, it either serves as the starting point ‐ the ?

Semi-classical buckling of stiff polymers

, 2007
A quantitative theory of the buckling of a worm like chain based on a semi-classical approximation of the partition function is presented. The contribution of thermal fluctuations to the force-extension relation that allows to go beyond the classical ...
