Contact mechanics for randomly rough surfaces

BNJ Persson - Surface science reports, 2006 - Elsevier
When two solids are squeezed together they will in general not make atomic contact
everywhere within the nominal (or apparent) contact area. This fact has huge practical …

Solid friction from stick–slip down to pinning and aging

T Baumberger, C Caroli - Advances in Physics, 2006 - Taylor & Francis
We review the present state of understanding of solid friction at low velocities and for
systems with negligibly small wear effects. We first analyze in detail the behavior of friction at …

Pick and place process for uniform shrinking of 3D printed micro-and nano-architected materials

T Mori, H Wang, W Zhang, CC Ser, D Arora… - Nature …, 2023 - nature.com
Two-photon polymerization lithography is promising for producing three-dimensional
structures with user-defined micro-and nanoscale features. Additionally, shrinkage by …

Frictional weakening of slip interfaces

B Weber, T Suhina, AM Brouwer, D Bonn - Science advances, 2019 - science.org
When two objects are in contact, the force necessary to overcome friction is larger than the
force necessary to keep sliding motion going. This difference between static and dynamic …

Investigation on dynamics performance of multibody system with rough surface

G Wang, L Wang, Y Yuan - Applied Mathematical Modelling, 2022 - Elsevier
This investigation aims to validate the effect of the rough contact surface on the dynamic
responses of the multibody system based on the fractal theory. Firstly, a two-dimensional …

Frequency and time simulation of squeal instabilities. Application to the design of industrial automotive brakes.

GV Des Roches - 2011 - theses.hal.science
Brake squeal is a common noise problem encountered in the automotive industry. Higher
friction coefficients and weight reduction recently led to higher vibration levels in the audible …

The mechanics of seismic faulting: Recent advances and open issues

A Bizzarri - La Rivista del Nuovo Cimento, 2014 - Springer
In the early'60s the fracture mechanics was mainly focused on tensile cracks (of prominent
importance in engineering problems) and later on shear, antiplane cracks. Since these …

[HTML][HTML] The frequency response of dynamic friction: enhanced rate-and-state models

A Cabboi, T Putelat, J Woodhouse - Journal of the Mechanics and Physics …, 2016 - Elsevier
The prediction and control of friction-induced vibration requires a sufficiently accurate
constitutive law for dynamic friction at the sliding interface: for linearised stability analysis …

Velocity dependence of friction of confined hydrocarbons

IM Sivebaek, VN Samoilov, BNJ Persson - Langmuir, 2010 - ACS Publications
We present molecular dynamics friction calculations for confined hydrocarbon “polymer”
solids with molecular lengths from 20 to 1400 carbon atoms. Two cases are considered:(a) …

Effect of surface pattern on the adhesive friction of elastomers

F Wu-Bavouzet, J Cayer-Barrioz, A Le Bot… - Physical Review E …, 2010 - APS
