Effect of Friction on Dense Suspension Flows of Hard Particles
, 2017 We use numerical simulations to study the effect of particle friction on suspension flows of non-Brownian hard particles. By systematically varying the microscopic friction coefficient $\mu_p$ and the viscous number $J$, we build a phase diagram that ...

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing
Advanced Functional Materials, EarlyView.A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014 Within the frame of this work, the influence of four very well-known and often used thermochemical treatments (carburizing, carbonitriding, nitriding and nitrocarburizing) of steel rolling paths applied on rolling-friction coefficient has been studied ...

Considerations on finding the rolling and spinning friction coefficients
MATEC Web of Conferences, 2018 The complex motion from a point contact has as consequence the occurrence of a friction torsor within both spinning and rolling friction exist. Additionally, recent researches showed that the two friction moments, spinning and rolling torques, are not ...

Transactions of the Japan Society of Mechanical Engineers, 1961 There are several hypotheses on the mechanism of rolling friction, but they are not recognized as an established theory. Authors recently reported the experimental research on the high speed rolling friction and clarified the many characteristics which cannot be expounded by the former hypotheses.

A new analytical approach for the velocity field in rolling processes and its application in through-thickness texture prediction [PDF]
, 2014 A new analytical model is presented that expresses kinematically admissible velocity fields in rolling processes. Opposed to conventional streamline approaches, the current model does not force the material to flow along the prescribed lines, but ...

Advanced Functional Materials, EarlyView.Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.
