Dear all,

Herewith I want to announce the release of the frictional rolling contact model CONTACT version 12.1.

The main changes with respect to earlier versions of the program are as follows:

• Achieved a 100-fold speedup for solving larger normal contact problems.
• Improved the documentation of the viscoelastic part of CONTACT and
  provided an example of its use.
• Distinguished free and premium features in the software, the latter
  requiring a valid license file.

For the full release-notes or more information on the program refer to the website www.kalkersoftware.org.

Regards, Edwin

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.

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

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;

"Error in job Job-1: Internal error in look-up table generation.  Check that dataline entries are sufficient to describe the dependence in all independent variables"

Can anyone please help me to get rid of error?

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

APS March Meeting Focus session: "Tribophysics: Friction, Fracture and Deformation Across Length Scales"

March 21 - 25, 2011, Dallas, Texas
Details at http://www.aps.org/meetings/march/scientific/focus2.cfm#12.7.3

Invited speakers: Michael Marder (Univ. of Texas); Julia Greer (Caltech)

Organizers: Robin Selinger (Kent State), Jacqueline Krim (NCSU), Noam Bernstein (NRL)

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 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. Eran Bouchbinder eran.bouchbinder@weizmann.ac.il

Dear all,

 The programme for the course on "Contact mechanics with the CONTACT software", to be held October 28th-29th 2010 in Delft, the Netherlands, is now available via the registration form on our website www.kalkersoftware.org.

Best regards,

Edwin Vollebregt

Dear all,

 On Thursday 28th and Friday 29th of October 2010, we will organise a course on using the CONTACT software at Delft University of Technology in the Netherlands.

The aims of the course are:

The Graduate School MUSIC (Multiscale Methods for Interface Coupling) invites to its first Summer School on Multiscale and Multiphysics Modelling of Interfaces at Leibniz Universitaet Hannover, Germany, from 15 to 17 September 2010.

Submissions are now closed for oral presentations to WOM 2011, however, contributions are invited for stand-alone posters. WOM 2011 is to take place in Philadelphia, USA - April 3-7 next year.  It will focus on both the fundamental and applied aspects of wear and friction of materials at the macro-, micro- and nano-scale. Special emphasis will be placed on wear issues in harsh environments, energy conversion, and debris particle generation and its impact on the environment.
