WebApr 14, 2024 · As far as the knowledge of the seabed is concerned, both for safe navigation and for scientific research, 3D models, particularly digital bathymetric models (DBMs), are nowadays of fundamental importance. This work aimed to evaluate the quality of DBMs according to the interpolation methods applied to obtain grid format 3D surfaces from … WebFeb 21, 2024 · Discussion and conclusions. In this paper, a tangential contact model associated with contributions of both elastically and plastically deformed asperities to the total tangential force was proposed. The model is based on non-Gaussian rough surfaces, whose height probability density function is generated by Pearson system of frequency …

WebFeb 15, 1999 · Abstract A method of determination of the basic morphology parameters of rough metal surfaces with periodic and random components of surface roughness by means of laser light scattering is presented. The method is based on interpreting the angular distribution of the laser light intensity scattered from such surfaces.

WebApr 1, 2024 · The paper showed results of exponential correlation functions with kh = 1. For CST, it was reported that rough surface simulations were performed for Gaussian correlation functions with h = 0.1 ... WebA method of replicating randomly rough surfaces fabricated in photoresist has been developed, enabling comparisons of the scattered light to be made between identical diffusers made from different materials. Experimental measurements on one-dimensional metal (gold) and dielectric surfaces are presented, and some initial comparisons with … WebJul 1, 2024 · Herein, based on the random process model of Nayak (1973) and the profilometric theory (Greenwood, 1967), an analytical version of the incremental equivalent circular contact model is formulated for the contact between Gaussian rough surfaces and rigid flats. This new proposed model is applicable to both the purely elastic contact and … sensitivity to chemical smells
