Spatial transportation of the beam on a bifilar fastening [PDF]

open access: yesFME Transactions, 2022
The complex problem of the spatial motion of the "trolley-beam" mechanical system is investigated. Three stages are considered: 1) movement of the beam on a bifilar suspension to the movable trolley; 2) movement of the beam after the breakage of one ...

A Thermodynamically Consistent, Microscopically-Based, Model of the Rheology of Aggregating Particles Suspensions

open access: yesEntropy, 2022
In this work, we outline the development of a thermodynamically consistent microscopic model for a suspension of aggregating particles under arbitrary, inertia-less deformation.

Dynamic response studies on aggregation and breakage dynamics of colloidal dispersions in stirred tanks [PDF]

open access: yes, 2008
Aggregation and breakage of aggregates of fully destabilized polystyrene latex particles in turbulent flow was studied experimentally in both batch and continuous stirred tanks using small-angle static light scattering. It was found that the steady-state

Ecological biomechanics of damage to macroalgae

open access: yesFrontiers in Plant Science, 2022
Macroalgae provide food and habitat to a diversity of organisms in marine systems, so structural damage and breakage of thallus tissue can have important ecological consequences for the composition and dynamics of marine communities.

Modeling Water Droplet Freezing and Collision with a Solid Surface

open access: yesEnergies, 2021
Water droplets released from the sea surface represent one of the major causes of ice accretion on marine vessels. A one-dimensional model of the freezing of a spherical water droplet moving in cold air was developed. The crystallization model allows one

Shear behavior of coarse aggregates for dam construction under varied stress paths

open access: yesWater Science and Engineering, 2008
Coarse aggregates are the major infrastructure materials of concrete-faced rock-fill dams and are consolidated to bear upper and lateral loads. With the increase of dam height, high confining pressure and complex stress states complicate the shear ...

Physical and chemical properties of yarn sized with a composition based on starch, PVA and HYPAN [PDF]

open access: yesE3S Web of Conferences, 2023
This article deals with the development of a new composition of a polymer composition for dressing cotton yarn. The optimal concentration of the dressing polymer composition, which is 50 g/kg, against the starch-based dressing is 70 g/kg, i.e., the ...
