Multifunctional and Reprogrammable Magnetoactive Graphene Oxide Origami

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A magnetic graphene oxide film is developed that enables rapid, precise, and programmable shape morphing under magnetic actuation. The MGO sensoriactuators feature humidity‐tunable performance and integrated sensing–actuation capability. Customized origami structures can be easily created by simple cutting and folding, while reusable magnetic stickers ...

Using stability analysis of discrete elastic systems to study the buckling of nanostructures

Archives of Mechanics, 2012
Stubility/instability criteria of discrete elastic systems are used to study the buckling of nanostructures. The deformation of nanostructures is simulated by solving the nonlinear equations of molecular mechanics.

Dynamic Response of Spherically Curved Laminated Plate Subjected to Sudden Loading

Journal of Engineering, Volume 2026, Issue 1, 2026.
This study investigated the dynamic response of simply supported spherical laminated composite plates with square vertices, composed of graphite/epoxy material, under sudden loading. The research examined the influence of stacking sequence, thickness variation, and type of loading using the finite element method (FEM).

Rippling Instabilities in Suspended Nanoribbons

, 2011
Morphology mediates the interplay between the structure and electronic transport in atomically thin nanoribbons such as graphene as the relaxation of edge stresses occurs preferentially via out-of-plane deflections. In the case of end-supported suspended

Analytical displacement-controlled solutions to bifurcation buckling and post-buckling of soft functional beams with constrained ends

, 2023
Abstract The soft functional beams in many modern devices usually have elastic bifurcation buckling under the end-displacement control, which is essential to their consequent functions. The concise and accurate analytical solutions for the buckling and post-buckling analysis are needed to fast design these beams. Here we derive some closed-form
