Role of surface texture and roughness parameters

In the present investigation, various kinds of surface textures were attained on the steel plates. Roughness of the textures was varied using various grinding or polishing methods. The surface textures were characterized in terms of roughness parameters using an optical profilometer. Then experiments were conducted using an inclined pin-on-plate sliding apparatus to identify the role of surface...

Quantification of Deformation-induced Surface Roughening Using Modified Roughness Parameters and Fourier Filtering

Surfaces of metal sheets initially contain high frequency, low amplitude roughness components imparted during the rolling process. When plastic deformation is imposed, the amplitude of these free surface components increases, producing various kinds of morphological features including randomness, periodicity and waviness. The features often control key functional aspects of a metal surface, suc...

Soil surface roughness quantification using DEM obtained from UAV photogrammetry

The soil surface roughness is one of the most susceptible to variation in time and space characteristic, and depends on many variables like cultivation practices or soil aggregation. Various indices are used for its quantification, in microscale soil roughness is commonly expressed by HSD calculated from DEM of small sample area. The source of DEM can be close range photogramethry or laser scan...
