A non-periodic two scale asymptotic method to take account of rough topographies for 2D elastic wave propagation [PDF]

open access: yes, 2013
International audienceWe propose a two scale asymptotic method to compute the effective effect of a free surface topography varying much faster than the minimum wavelength for 2-D P-SV elastic wave propagation.

Surface Topography of Nitrided Steel Surfaces

open access: yesJournal of Physics: Conference Series, 2019
© Published under licence by IOP Publishing Ltd. The effect of nitrocarburizing were investigated for two different steels, 42CrMo4 and 25CrMo4, with objective to evaluate the influence of initial surface topography on the resulting nitrocarburized surface with regard to surface topography and thickness of the compound layer.

Review of reflective fiber optic sensors for surface topography measurement

open access: yesJournal of Measurement Science and Instrumentation, 2018
Different from the traditional contact surface topography measurement,reflective intensity-modulated fiber optic sensor(RIM-FOS)has the unique advantages of non-contact nondestructive detection.This paper briefly introduces the principle and performance ...

Evolution of Metal Surface Topography during Fatigue

open access: yesMetals, 2017
Changes in surface topography reflect the state of fatigue damage. In this paper, a new method to characterize metal surface topography during fatigue has been proposed. Firstly, we acquired surface topography images based on machine vision and separated

De-icing performance evolution with increasing hydrophobicity by regulating surface topography

open access: yesScience and Technology of Advanced Materials
It is of great significance to grasp the role of surface topography in de-icing, which however remains unclear yet. Herein, four textured surfaces are developed by regulating surface topography while keeping surface chemistry and material constituents ...

Bouncing or sticky droplets: impalement transitions on superhydrophobic micropatterned surfaces

open access: yes, 2005
When a liquid drops impinges a hydrophobic rough surface it can either bounce off the surface (fakir droplets) or be impaled and strongly stuck on it (Wenzel droplets).

Tailoring the frictional properties of granular media

open access: yes, 2011
A method of modifying the roughness of soda-lime glass spheres is presented, with the purpose of tuning inter-particle friction. The effect of chemical etching on the surface topography and the bulk frictional properties of grains is systematically ...
