Two Nano-Tribology postdoctoral positions in Tel Aviv University

Submitted by shmuel on Mon, 02/20/2012 - 11:38

Two postdoctoral positions are available in the group of Prof. M. Urbakh in lively Tel-Aviv. Topics are centered around nano and micro-scale tribology (friction, dissipation, adhesion, wear) involving theory, modeling, and computer simulation of frictional and nonlinear
dissipation phenomena.

The projects focus on: (i) studies of friction at micropatterened surfaces with biomimetic and sensing applications, and (ii) novel approaches to control frictional response at the nanoscale through application of electric field, light and force modulations.

List of conferences in contact mechanics and related fields

Submitted by Edwin Vollebregt on Wed, 09/28/2011 - 07:44

Dear all,

At our website we maintain a list of upcoming conferences on contact mechanics and related fields, e.g. solid mechanics, tribology, railway vehicle dynamics, etc.

Which conferences and other events do you attend? Send me a note and I'll add them to the list.

Best wishes,

Edwin Vollebregt

Modeling contact problem in ABAQUS

Submitted by drmaity on Wed, 08/10/2011 - 13:12

Dear all,

In my FE model (pin on disc), I would like to define a contact property between pin and disc with a friction defination available in ABAQUS. I have assumed that friction coefficient depends on parameters like slip rate, pressure and temperature only. When i used friction coefficients with slip rate and pressure, model works without any error but if i use friction coefficients with slip rate, pressure and temperature, the model doesn't work and come up with following errors;

Can you imagine a mechanical system that is stable without friction, but suffers a flutter instability when friction is 'added'?

flutter instability

Have you ever seen a structure subject to flutter instability?

Can flutter instability be connected to dry friction?

We provide positive answers to the above questions, watch the video at

non-linear friction in FE

Submitted by Chris W Smith on Tue, 11/02/2010 - 14:57

research

friction

non-linear

We are looking at implementing a non-linear model with friction, and at least in the first place for statics. We haven't found much in the literature on non-linear models for friction in FE.

Anyone any advice on key papers to read ?

Thanks,

Chris
