The premium version of CONTACT provides the so-called "Extended CONTACT" model. This delivers significant advances for wheel-rail contact with respect to Kalker's original theories:

  • Conformal contact. Falling friction. 3rd body layer.
  • Fast and detailed calculation. Extended support.
These extensions are presented in scientific papers [Vollebregt2014d], [Vollebregt2014c], [Vollebregt2014a] and [Vollebregt2012a] that are listed on the publications page.
