摘要
Abstract
A new contact model among rough surfaces was presented based on fractal theory. Y-K fractal model was revised to include all of the elastic, elastic-plastic, and fully plastic deformation regimes for asperity of the fractal surfaces. The two dimensional Y-K model was extended to a new one for three dimensional fractal contact. It is shown that simulation results from revised fractal contact agree with test one better than Y - K contact model, especially under large load. Thus the presented revised fractal contact model can provide more reasonable method for the prediction of contact behaviors among rough surfaces with more accurate than that of Y-K model relatively.关键词
