Measurement of interface pressure in interference fits [PDF]
, 2005 When components such as bearings or gears are pressed onto a shaft, the resulting interference induces a pressure at the interface. The size of this pressure is important as many components fail because fatigue initiates from press-fit stress ...

Expressions of Rock Joint Roughness Coefficient Using Neutrosophic Interval Statistical Numbers [PDF]
Symmetry, 2017 In nature, the mechanical properties of geological bodies are very complex, and their various mechanical parameters are vague, incomplete, imprecise, and indeterminate. However, we cannot express them by the crisp values in classical probability and statistics.

Science and Engineering of Composite Materials, 2021 The joint roughness has an influence on the uniaxial compressive strength (UCS) and characteristic strength of the rock, but the relationship of the influence is yet to be obtained. In this article, the influence of the size of the rock with rough joints

Tracer Dispersion in Rough Open Cracks [PDF]
, 1998 Tracer dispersion is studied in an open crack where the two rough crack faces have been translated with respect to each other. The different dispersion regimes encountered in rough-wall Hele-Shaw cell are first introduced, and the geometric dispersion ...

Bridge expansion joint in road transition curve: effects assessment on heavy vehicles [PDF]
, 2017 Properly-designed road surfaces provide a durable surface on which traffic can pass smoothly and safely. In fact, the main causes that determine the structural decay of the pavement and its parts are the traffic loads.

Particle Resuspension in Turbulent Boundary Layers and the Influence of Non-Gaussian Removal Forces [PDF]
, 2013 The work described is concerned with the way micron-size particles attached to a surface are resuspended when exposed to a turbulent flow. An improved version of the Rock'n'Roll model (Reeks and Hall, 2001) is developed where this model employs a ...

Friction of Teflon-S-coated Ti-6Al-4V under conditions of oscillatory relative motion [PDF]
, 1990 An extendable prosthesis for implantation in a human leg has been developed. The friction forces during extension of the prosthesis must be low, so a coating of Teflon-S was applied to the sliding surfaces. During walking, damage can occur as a result of

Sustainability, 2022 Accurate determination of the surface roughness is of significant importance in estimating the mechanical and hydraulic behaviors of rock joints. The correlation between joint roughness coefficient (JRC) and various statistical roughness parameters calculated from digitized Barton’s roughness profiles was explored with Pearson’s correlation coefficient
