Sliding Wear Modeling of Artificial Rough Surfaces

open access: yesInternational Journal of Science and Engineering, 2012
Surface roughness plays an important role in machine design. In the micro-scale when two engineering surfaces are brought into contact, the real contact area occurs at isolated point of asperity. Wear is one of some effects of contacting surfaces.
