Universal behavior of internal friction in glasses below T : anharmonicity vs relaxation [PDF]
Comparison of the internal friction at hypersonic frequencies between a few K and the glass transition temperature Tg for various glasses brings out general features. At low temperature, internal friction is only weakly dependent on the material. At high

Arabica coffee flow properties assessed using different roasts and particle sizes during storage
Flowability of agricultural products is an important factor to be considered at post-harvest, thus impacting directly on number of operations and the design of machinery. This study aimed to evaluate and determine the K coefficient and flow properties as

Reflections on Friction in Quantum Mechanics
Distinctly quantum friction effects of three types are surveyed: internalfriction, measurement-induced friction, and quantum-fluctuation-induced friction.

Existence of long‐time solutions to dynamic problems of viscoelasticity with rate‐and‐state friction [PDF]
We establish existence of global solutions to a dynamic problem of bilateral contact between a rigid surface and a viscoelastic body, subject to rate‐and‐state friction.

Theoretical and computational validation of the Kuhn barrier friction mechanism in unfolded proteins
A long time ago, Kuhn predicted that long polymers should approach a limit where their global motion is controlled by solvent friction alone, with ruggedness of their energy landscapes having no consequences for their dynamics.

Research on the carbon emission reduction of internal combustion engines by reducing friction work [PDF]
The increase in carbon dioxide emissions is a key factor leading to the warming of the Earth’s climate system and the intensification of the greenhouse effect. Internal combustion engines have a significant impact on carbon emissions.

Internal friction in advanced Fe-Al intermetallics [PDF]
We have measured the internal friction and the dynamic modulus of an Fe–38 at.% Al alloy using a forced torsion pendulum working between 10−3 and 10 Hz. The measurements have been carried out as a function of temperature (from room temperature to 1200 K)

It is emphasized that a distribution function in both the dislocation loop lengths and obstacle strengths must be considered to develop a quantitative theory for the hysteretic dissipation of energy. That is when dislocation surmounts and undulating internal stress field and the break-away is restricted by a restoring force considered to be that of ...

Mechanical Spectroscopy of Ti-15Zr-based Alloys with Mo Addition [PDF]
In this paper, the effect of substitutional Mo amounts in internal friction and interstitial diffusion mechanisms was analyzed in Ti-15Zr-based alloys. Mechanical spectroscopy was obtained from room temperature up to 730 K with frequencies between 1 Hz ...
