...G. F. Wang; X. M. Liang; D. Yan The accurate calculation of the real contact area between rough surfaces is a key issue in tribology. In this paper, based on the geometrical information of total contact area and the number of contact patches with respect to surface separation, a new method...

...Lei-Tao Li; Xuan-Ming Liang; Yu-Zhe Xing; Duo Yan; Gang-Feng Wang The measurement of the real contact area between rough surfaces is one of the most challenging problems in contact mechanics and is of importance to understand some physical mechanisms in tribology. Based on the frustrated total...

...Isami Nitta; Yoshio Matsuzaki To clarify the sealing characteristics of metal gasket seals, leakage rates of gas and the real contact area of the seal surfaces were measured under several closing loads. The static seal consisted of a ring-shaped copper gasket and the two steel flanges that held...
