摘要

Four different numerical approaches to calculate strains and stresses in the contact zone are investigated. The examination is performed considering as example the transition process of a wheel passing a crossing. A dynamic, a quasi-static, a static and a Hertzian model are available. The four elasto-plastic models for rolling contact are evaluated and the results are compared.
