Adaptive solution of rolling contact using boundary element method

In this paper, the fast and adaptive calculation of large number of consecutive rolling contact problems is discussed. A special BEM method is proposed for the solution of non-Hertz and conformal contact. The attention is paid on the appropriate choice of the potential contact area so that it contains completely the real contact area while it is as small as possible to reduce computing time, on good initial estimation to speed up convergence, and on the adaptability to various possible geometry and loading situations.
