Surface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface … See more Surface roughness can be regarded as the quality of a surface of not being smooth and it is hence linked to human (haptic) perception of the surface texture. From a mathematical perspective it is related to the spatial variability … See more • Discontinuity (Geotechnical engineering) • Rugosity • Normal contact stiffness • Surface finish See more In Earth Sciences (e.g., Shepard et al., 2001; Smith, 2014 ) and Ecology (e.g., Riley et al., 1999; Sappington et al., 2007 ) surface roughness has a quite broad meaning (e.g. Smith, 2014), with multiple definitions, and generally it is considered a multi-scale property … See more • Surface Metrology Guide • Roughness terminology Archived 2016-03-03 at the Wayback Machine • Ra and Rz description See more
