Announcing free version of Kalker's rolling contact model

Dear all,

Herewith I would like to announce that we have decided to make our CONTACT software publicly available. You can obtain a free copy at the web-site www.kalkersoftware.org. We hope that the software is beneficial to you. We further hope that you give us helpful feedback in return.

This CONTACT software concerns Prof. J.J. Kalker's variational theory for rolling contact. It is particularly suited for the detailed study of the traction and slip distributions in the contact zone. It is restricted to homogeneous bodies of elastic and visco-elastic materials and to concentrated contact", i.e. with essentially flat geometries in and near the contact zone. The main type of application concerns the wheel/rail interface. The program uses a boundary element approach with analytic influence coefficients. As such it is much faster than finite element approaches.

For more details on the program, its user guide and a list of publications refer to the web-site.

With best wishes,

Edwin Vollebregt

Dear Edwin;

I have not many ideas about the program, and just i started with this program from its help, have you some detailed examples about the program? and if any of the bodies studied has a velocity, how can study this case?

 Thank you

Dear mosab and others,

 If you have questions or remarks on our CONTACT software, please contact us at support@kalkersoftware.org.

Thanks, Edwin

Dear all,

Herewith I want to announc the release of CONTACT version 10.1.

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

  • Added the FASTSIM algorithm for quickly approximating the tangential stresses.
  • Speed-up of the computations using parallelisation on multi-core PC's.
  • Improved input-options for the subsurface stress calculation, added an example and plot-routine as well.
  • Allow for comments in and improved handling of the user input file.

For more information on the program and the updates refer to the website www.kalkersoftware.org.

Regards, Edwin
