  text: A model to calculate the locally resolved tangential contact forces of the
    wheel rail contact with respect to contact kinematics, material and surface properties
    as well as temperature is introduced. The elasticity of wheel and rail is modeled
    as an elastic layer consisting of point contact elements connected by springs
    to each other and to the wheel. Each element has two degrees of freedom in tangential
    directions. The resulting total stiffness matrix is reduced to calculate only
    the position of the elements in contact. Friction forces as well as contact stiffnesses
    are incorporated by a nonlinear force-displacement characteristic, which originates
    from a detailed contact model. The contact elements are transported through the
    contact zone in discrete time steps. After each time step an equilibrium is calculated.
    For all elements, their temperature and its influence on local friction are regarded
    by calculating friction power and temperature each time step.
