WOM 2013 - Keynote Speakers Announced

Wom 2013 keynote speakers and their topics have been announced:

Dr Ali Erdemir
Argonne National Laboratories, USA
Innovative surface engineering strategies for mitigating wear of materials under extreme conditions

Dr Michael Moseler
FhG-IWM Freiburg, Germany
Atomistic understanding of wear in carbon tribomaterials

Frequency analysis with Contact constraint

Hi,

 

I am trying to analysis a model in ABAQUS with a plate bolted to the Bracket top surface at 4 ends. I have to define contact between them (and also bolted at 4 ends) to get the Modal frequency. But When I searched for it, I got the answer that contact doesn't work with Modal analysis as contact is a nonliner problem and Modal Analysis only solves linear problem.

 

WOM 2013 - First Announcement and Call for Papers - deadline 1 June 2012

The 19th International Conference on Wear of Materials with take place in Portland, Oregon, USA, 14-18 April 2013. Two typed of papers ar invited: 1) full-length research-qulity papers that involve materials aspects of wear, wear analysis and wear modeling, and 2)shorter, concise case studies. Both categories of papers will be peer reviewed for technical quality.

 All submissions should be made online at www.wearofmaterialsconference.com by 1 June 2012

 

 

Postdoc in MD Simulations and Theory of NanoFriction (Erio Tosatti's Group, SISSA, Trieste)

Funded through SNF SINERGIA Project ‘Understanding nanofriction and dissipation across phase transitions’, we open in SISSA a postdoctoral position (‘assegno di ricerca’) in the area centered around nanoscale tribology (friction, dissipation, adhesion, wear) involving modeling, theory, and molecular dynamics computer simulations of nanofrictional and nonlinear dissipation phenomena, especially in presence of continuous phase transitions.

Two Nano-Tribology postdoctoral positions in Tel Aviv University

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.

EXTENDED ABSTRACT SUBMISSION: Nanobrücken II: A Nanomechanical Testing Workshop, March 22-23, 2012, INM Saarbrücken, Germany

Dear Colleague:

You are cordially invited to attend Nanobrücken II:  A Nanomechanical Testing Workshop, jointly presented by INM - Leibniz Institute for New Materials and Hysitron, Inc., with co-sponsorship from the JEOL company. This is the second workshop in the Nanobrücken series. The workshop's scope has been broadened, and the abstract submission deadline is now February 19, 2012.

List of conferences in contact mechanics and related fields

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

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;

non-linear friction in FE

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

A new postdoc position is available

A new postdoctoral position in continuum mechanics is available at the Weizmann Institute of Science. Candidates should have a strong background in physics and/or theoretical mechanics, as well as experience with analytical and computational methods for solving partial differential equations. Possible projects include the mechanics of frictional sliding, the mechanics of biomaterials, the mechanics of glassy materials and dislocation-mediated plasticity. Highly motivated candidates are requested to send their CV, publications list and statement of research interests to Dr.
