Mechanics and fatigue in wheel/rail contact : proceedings of the Third International Conference on Contact Mechanics and Wear of Rail/Wheel Systems, Cambridge, U.K. July 22-26, 1990 /

These proceedings demonstrate the increasing interest and importance of contact mechanics and wear to the railway industry. The 27 contributions succeed in sustaining a balance between mechanics and metallurgy, theory and practice, and will be of considerable interest to those engaged in research, a...
