On the convergence of stresses in fretting fatigue [PDF]

open access: yes, 2016
Fretting is a phenomenon that occurs at the contacts of surfaces that are subjected to oscillatory relative movement of small amplitudes. Depending on service conditions, fretting may significantly reduce the service life of a component due to fretting ...

On actions for (entangling) surfaces and DCFTs

open access: yes, 2018
The dynamics of surfaces and interfaces describe many physical systems, including fluid membranes, entanglement entropy and the coupling of defects to quantum field theories.

A local view on the role of friction and shape [PDF]

open access: yes, 2017
Leibniz said "Naturam cognosci per analogiam": nature is understood by making analogies. This statement describes a seminal epistemological principle.

The TDNNS method for Reissner-Mindlin plates [PDF]

open access: yes, 2017
A new family of locking-free finite elements for shear deformable Reissner-Mindlin plates is presented. The elements are based on the "tangential-displacement normal-normal-stress" formulation of elasticity.

Lipid membranes with an edge

open access: yes, 2002
Consider a lipid membrane with a free exposed edge. The energy describing this membrane is quadratic in the extrinsic curvature of its geometry; that describing the edge is proportional to its length.

Ambiguity of black hole entropy in loop quantum gravity [PDF]

open access: yes, 2005
We reexmine some proposals of black hole entropy in loop quantum gravity (LQG) and consider a new possible choice of the Immirzi parameter which has not been pointed out so far.

Isometric bending requires local constraints on free edges

open access: yes, 2019
While the shape equations describing the equilibrium of an unstretchable thin sheet that is free to bend are known, the boundary conditions that supplement these equations on free edges have remained elusive.

Evolution of plane curves with a curvature adjusted tangential velocity

open access: yes, 2011
We study evolution of a closed embedded plane curve with the normal velocity depending on the curvature, the orientation and the position of the curve.

Motion of an Adhesive Gel in a Swelling Gradient: a Mechanism for Cell Locomotion [PDF]

open access: yes, 2003
Motivated by the motion of nematode sperm cells, we present a model for the motion of an adhesive gel on a solid substrate. The gel polymerizes at the leading edge and depolymerizes at the rear.

Screen‐Printed Flexible Piezoelectric Force Sensor Array with Electromagnetic Interference Shielding

open access: yesAdvanced Engineering Materials, EarlyView.
This article introduces a flexible screen‐printed piezoelectric sensor array designed for low‐frequency healthcare applications such as tactile sensing and cardiovascular monitoring. The device integrates interface electronics enabling the simultaneous acquisition of up to 128 signals, along with flexible EMI shielding that significantly reduces noise ...
