An efficient mixed variational reduced order model formulation for non-linear analyses of elastic shells [PDF]

open access: yes, 2017
The Koiter-Newton method had recently demonstrated a superior performance for non-linear analyses of structures, compared to traditional path-following strategies.

Approximate Stability Analysis of Omega‐Stringer Stiffened Composite Panels

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Thin‐walled composite structures are widely used in weight‐critical applications such as aircraft and spacecraft. However, ensuring the stability of such structures under various load cases remains a key challenge in their design and optimization.

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

open access: yesJournal 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 ?

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

open access: yesVietnam 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)

Semi-classical buckling of stiff polymers

open access: yes, 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 ...

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

open access: yesSmartBot, 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 ...

Membrane buckling induced by curved filaments

open access: yes, 2009
We present a novel buckling instability relevant to membrane budding in eukaryotic cells. In this mechanism, curved filaments bind to a lipid bilayer without changing its intrinsic curvature.

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

open access: yesFatigue &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

Experimental study of a three dimensional cylinder-filament system

open access: yes, 2015
This experimental study reports on the behavior of a filament attached to the rear of a three- dimensional cylinder. The axis of the cylinder is placed normal to a uniform incoming flow and the filament is free to move in the cylinder wake.
