This unique book presents a coherent asymptotic approach to the analysis of elastohydrodynamic lubrication (EHL) problems for heavily loaded line and point contacts. This approach leads to unified asymptotic equations for line and point contacts as well as stable numerical algorithms for the solution of these problems. Suitable for engineering and applied mathematics students, this is also a unique resource for researchers and practitioners who want to fine tune their solution methods and design better numerical methods to tackle practical EHL problems.
