Temperature distribution effects on buckling behavior of smart heterogeneous nanosize plates based on nonlocal four-variable refined plate theory

open access: yesInternational Journal of Smart and Nano Materials, 2016
This work presents a theoretical study for thermo-mechanical buckling of size-dependent magneto-electro-thermo-elastic functionally graded (METE-FG) nanoplates in thermal environments based on a refined trigonometric plate theory.

Triangular buckling patterns of twisted inextensible strips

open access: yes, 2010
When twisting a strip of paper or acetate under high longitudinal tension, one observes, at some critical load, a buckling of the strip into a regular triangular pattern.

“Tone‐Arm” Neuromodulation MEMS Microcoil for In Vivo Imaging

open access: yesSmall, EarlyView.
ABSTRACT Implantable neural interfaces have revolutionized neuromodulation by enabling bidirectional communication between neural circuits and external devices. Yet, existing modalities face important challenges in precision, high invasiveness, and compatibility with advanced in vivo imaging systems.

Study of the Buckling Behavior of Completion Strings for Ultra-Deep Gas Wells

open access: yesShiyou jixie, 2020
Due to high wellbore temperature and pressure, ultra-deep high temperature and high pressure (HTHP) gas wells have a high downhole string buckling risk that are very likely to cause string failure and worsened washout etc. problems.

The buckling of a swollen thin gel layer bound to a compliant substrate [PDF]

open access: yes, 2007
Gels are used to design bilayered structures with high residual stresses. The swelling of a thin layer on a compliant substrate leads to compressive stresses.

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.

Mechanical Instabilities of Biological Tubes

open access: yes, 2012
We study theoretically the shapes of biological tubes affected by various pathologies. When epithelial cells grow at an uncontrolled rate, the negative tension produced by their division provokes a buckling instability.

Compression‐Tension‐Asymmetry and Stiffness Nonlinearity of Collagen‐Matrigel Composite Hydrogels

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 9, 6 March 2026.
Self‐assembled collagen hydrogel matrices are widely used in tissue engineering applications. These matrices stiffen and contract laterally under tension due to fiber alignment and soften and collapse under compression due to fiber buckling. It is demonstrated that filler materials, such as Matrigel, linearize the mechanical behavior of collagen ...

Tendon‐Driven Compliant Wheel‐Less Snake Robot for Undulatory Locomotion Using Conformable Ground Contacts

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This study presents a tendon‐driven compliant snake robot that uses globally applied vertical bending and axial twisting along its body to enable various gaits. Body deflection from compliance and weight passively generates the ground contact patterns required for locomotion.

Research on the Behavior of Coiled Tubing Running Based on Experiment

open access: yesShiyou jixie, 2018
The coiled tubing is subject to complex forces in downhole condition. The loads like gravity, liquid resistance, bending moment and torque, and environmental factors such as temperature and pressure make the coiled tubing prone to buckling during running.
