The Kalker book of tables for non-Hertzian contact described in a previous work from the authors provides creep forces, but the moment generated in the contact patch is not available. The extended Kalker book of tables for non-Hertzian contact (KBTNH) presented in this paper provides creep forces, as well as the moment. The paper …
As shown in Fig. 3, the analysis of rail damage simulation includes three main processes: simulation of dynamic interactions between wheel and rail, simulation of the rolling contact behavior and simulation of rail damages.This paper assesses the applicability of four non-Hertzian contact approaches (Kalker's 3D contact theory, Kik-Piotrowski, …

1. Chlorine dioxide is a yellow gas that dissolves easily in water, without altering its structure. 2. It is obtained by mixing sodium chlorite and dilute hydrochloric acid. 2. Chlorine dioxide gas dissolved in water is an oxidant. 3. Chlorine dioxide is pH selective and the more acidic the pathogen, the stronger the reaction.

Different approaches are used to incorporate these effects into VSD simulations. For the initial slope, the simplest approach is to scale the creepages by a reduction factor, the " percent _ kalker " value [13].For instance if the actual creepage is 1% and the percent _ kalker value is 30% then Kalker's theories are used with a fictitious …
Kalker's variational method is a preferred alternative for the calculation of non-Hertzian and multiple-point wheel–crossing contact. A computationally efficient combination of an extensive FE model with Kalker's variational method can be achieved by using Green's functions, which describes the dynamic behaviour of linear time-invariant ...

In this paper the theory of rolling contact is surveyed after a development of over 60 years. Six theories are significant at present: (1) the two-dimensional theory of Carter (1926); (2) the linear theory (Kalker 1967); (3) the complete theory (CONTACT, Kalker 1983–1990); (4) the British Rail Table Book (ca. 1980); (5) the theory of Shen, …
