Confinement induced instability of thin elastic film [PDF]

, 2005
A confined incompressible elastic film does not deform uniformly when subjected to adhesive interfacial stresses but with undulations which have a characteristic wavelength scaling linearly with the thickness of the film.

Bending Analysis of Thickness‐ and Shear‐Deformable Materially Imperfect Composite Shells With von Kármán‐Type Geometric Nonlinearities

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Geometrically nonlinear static analysis of materially imperfect composite doubly curved shells is investigated via the generalised differential quadrature method. The effects of both shear and thickness deformation are considered through a thickness‐ and shear‐deformable third‐order theory formulated in curvilinear coordinates, while the ...

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

Micro‐Texturized and Ultra‐Soft Dry Electrode for Motion‐Artifact Tolerant and Long‐Term Stable Wearable Electrophysiological Monitoring

Small, EarlyView.
A highly conformal and adhesive dry electrode is developed using a micro‐textured carbon black/PDMS composite. By leveraging spontaneous surface roughness for enhanced mechanical interlocking and integrating a stretchable serpentine interconnector, the device achieves robust skin contact and low impedance.

Pediatric Versus Adult Shear‐Induced Hemolysis—Are Age‐Related Blood Properties the Main Cause for Differences?

Artificial Organs, EarlyView.
Graphical summary of the experimental comparison of shear‐induced hemolysis in pediatric and adult blood using a Couette shearing device. Pediatric blood shows a trend toward lower increase in hemolysis at higher shear stress amplitudes, while no relevant differences are observed at low and intermediate stresses.

Life at high Deborah number

, 2009
In many biological systems, microorganisms swim through complex polymeric fluids, and usually deform the medium at a rate faster than the inverse fluid relaxation time.
