A systematic description and comparison on the methodology for solving the contact problem at the wheel-rail and wheel-roller interfaces have been done in terms of the geometric contact problem, normal contact problem, kinematic problem and tangential contact problem.
Thus we consider so-called unilateral contact problem.
In parallel with the contact problem for a plate with a volume rigid inclusion, we also consider the contact problem for an elastic plate with a thin inclusion.
The contact problem between two adjacent layers contains deformation compatibility of the contact surface.
The fracture deformation is calculated by solving the contact problem using the finite-element method.
Hopefully, by solving the metal contact problem, the fill factor can be improved.
The Kik Piotrowski model is a fast and non-iterative method to calculate normal contact problem.
Results are obtained for two- and three-dimensional problems, including a Hertzian contact problem.
Efficiency and accuracy of the resulting method is illustrated on a two-dimensional static contact problem and a three-dimensional dynamic contact problem as compared with ANSYS simulations.
The contact problem is solved using the assumed contact stress distribution method.
