The CONTACT library for MATLAB®


The CONTACT library for MATLAB® provides full access to the computational core of CONTACT from the MathWorks® MATLAB® software. This allows to build ones own model in an easy way on the basis of building blocks provided by the library.

results of CONTACT add-on

Separate building blocks are used such as cntc_setmaterialproperties for setting the material parameters, cntc_setgriddiscretization for the grid discretization and cntc_setcreepages for setting the creepages. Then the actual solution process is started with cntc_calculate, and the results may be retrieved using cntc_getforces, cntc_gettractions and cntc_getmicroslip.

Main benefits

  • Building your own programs using CONTACT's algorithms: fast, robust and versatile;
  • accessing all of CONTACT's features through an easy interface;
  • allowing each case to be built on previous results;
  • application in transient, dynamic scenarios.

Capabilities

The library provides all features of the input-file, without using an input-file:

  • options T=1, 2 and 3 for shifts, transient and steady rolling;
  • options L=0 to 4 for Coulomb friction and the velocity-dependent friction laws;
  • options M=0 to 4 for linearly elastic and visco-elastic materials, with optional interfacial layer;
  • options IBASE=1 to 9 for the undeformed distance specification, Hertzian or non-Hertzian;
  • full control over the creepage and/or the total force.
