The involved parameters are the mean flow, surface friction, size, intensity, and initial location of the vortex.
The biotribological tests, conducted under simulated hip joint conditions (friction, wear, Raman intensity ratio and polyethylene wear debris) were correlated with their surface and material properties.
Internal friction subsequently grew in intensity, fostered by mutual suspicion between the rival groups, by assassination attempts against the president, and by the increasingly oppressive methods employed by the government to silence its critics.
In the case of low sound intensity, the friction at the hole entrance is in charge of the dissipation of acoustic energy and it plays the dominant role in the noise suppression.
A microstructure with a bimodal grain size distribution of Al was formed via partial recrystallization after thermomechanical treatment of the sample sintered at 893 K, and two internal friction peaks with comparable intensity were detected.
Low-intensity ultrasound produces stable cavitation state, which can lead to intense friction and shear stress on the surrounding structures.
However, despite the vast amount of data in publication it is difficult to find satisfactory agreement (on friction factor and turbulence intensities for example) between investigations or to find data at very high Reynolds numbers where many industrial systems operate.
The effect of crack surface friction on mode II stress intensity factor (SIF) of a central slant crack in a plate uniformly loaded in uniaxial compression is quantified.
The contribution discusses the role, influence and the intensity of the friction in the process of the interface debonding in two subsequent fracture effects: the crack initiation and the crack propagation.
Correlations are summarized in the form of design charts for the key parameters, such as the area replacement ratio, the loading intensity, and the friction angle of the column material.
