Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

The joint roughness coefficient (JRC), introduced in Barton (1973) represented a new
method in rock mechanics and rock engineering to deal with problems related to joint …

This paper investigated shear-related roughness classification based on Fuzzy
comprehensive evaluation, and established a new strength model of natural rock joint. The …

This study introduces a double-exponential decay (DED) model to investigate the sampling
interval (δ)-dependent behavior of crack morphology roughness in steel fiber reinforced …

Surface roughness has a significant influence on the mechanical properties and service life
of a component. During face milling, surface roughness greatly varies in the tool step …

Rock joint roughness is one of the crucial parameters impacting the mechanical and
hydraulic properties of discontinuities. It can be conveniently estimated from two …

This study aims to evaluate the effectiveness of Ultrasonic-assisted drilling (UAD) of Glass
laminate aluminium reinforced epoxy (GLARE) at high cutting speeds (Spindle speeds …

Fractures provide preferential flow paths and establish the internal “plumbing” of the rock
mass. Fracture surface roughness and the matedness between surfaces combine to …

Natural rock joint permeability deviates from the classic fluid flow governing equations due
to the inherent fracture surface roughness (ie, contact points, spatial correlation, matching …

Rock joints play a crucial role in determining the behavior and stability of rock masses.
Despite their importance, there is a lack of devices for easily and accurately measuring joint …
