An ultrasonic approach for contact stress mapping in machine joints and concentrated contacts [PDF]

open access: yes, 2004
The measurement of pressure at a contact in a machine part is important because contact stresses frequently lead to failure by seizure, wear or fatigue.

An empirical method for calculating the roughness coefficient of structural plane with line-plane combination

open access: yesShuiwen dizhi gongcheng dizhi, 2023
The shear mechanical properties of structural plane are mainly determined by the surface roughness, and the roughness coefficient is the main method to characterize the roughness.

Some Remarks on the Use of Deterministic and Probabilistic Approaches in the Evaluation of Rock Slope Stability [PDF]

open access: yes, 2020
The rock slope stability assessment can be performed by means of deterministic and probabilistic approaches. As the deterministic analysis needs only representative values (generally, the mean value) for each physical and geo-mechanical parameter ...

Morphological classification method and data-driven estimation of the joint roughness coefficient by consideration of two-order asperity

open access: yesReviews on Advanced Materials Science, 2023
The roughness of the joint surface plays a significant role in evaluating the shear strength of rock. The waviness (first-order) and unevenness (second-order) of natural joints have different effects on the characterization of joint surface roughness. To

Process mapping of laser surface modification of AISI 316L stainless steel for biomedical applications [PDF]

open access: yes, 2009
A 1.5-kW CO2 laser in pulsed mode at 3 kHz was used to investigate the effects of varied laser process parameters and resulting morphology of AISI 316L stainless steel. Irradiance and residence time were varied between 7.9 to 23.6 MW/cm2 and 50 to 167 µs

A New Coefficient for Three Dimensional Quantification of Rock Joint Roughness [PDF]

open access: yesJournal of Korean Society For Rock Mechanics, 2012
Roughness of rock joint has generally been characterized based upon geometrical aspects of a two-dimensional surface profile. The appropriate description of joint roughness, however, should consider the features of roughness mobilization at contact areas under normal and shear loads.

Stochastic analysis of surface roughness

open access: yes, 2003
For the characterization of surface height profiles we present a new stochastic approach which is based on the theory of Markov processes. With this analysis we achieve a characterization of the complexity of the surface roughness by means of a Fokker ...
