Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

Deep Underground Science and Engineering, EarlyView.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...

Influence of clay mineralogy on undrained cyclic strength of sand with fines

Engineering Science and Technology, an International Journal
Soils in natural or reclaimed areas frequently contain a mixture of sand, silt, and clay, rather than consisting solely of clean sand. The influence of a small proportion of fine plastic particles within a sandy matrix on liquefaction resistance still ...

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

Investigating the Performance of Polytetrafluoroethylene and Polyoxymethylene Creasing Rules in the Package Conversion of Coated Paperboard

Packaging Technology and Science, EarlyView.
Two sets of creasing tools were designed and machined from polytetrafluoroethylene (PTFE) and polyoxymethylene (POM) in this study to improve the creasability of commercial dispersion‐coated paperboard. Their performance was evaluated by measuring the oil and grease resistance of the samples before and after creasing/folding and comparing the results ...

Note: "Lock-in accelerometry" to follow sink dynamics in shaken granular matter [PDF]

, 2014
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental Physics, but also for geophysical processes and construction on sediments or granular soils in areas potentially affected by earthquakes.

Sustainable Development Goals Applied to the Maritime Transportation Sector: Setting Sail for the Future

Natural Resources Forum, EarlyView.
ABSTRACT The 2030 Agenda for Sustainable Development aims to eradicate poverty, protect the environment, and promote prosperity through 17 Sustainable Development Goals (SDGs). Achieving these goals requires a multi‐sectoral approach. Maritime transportation, vital to the global economy, significantly contributes to several SDGs and plays a strategic ...

Field Test and Numerical Research of Blast-Induced Liquefaction in Calcareous Sand

Shock and Vibration
In recent years, the engineering losses caused by liquefaction of calcareous sand foundations have gradually increased. However, there are relatively few studies on the mechanism of blast-induced liquefaction in saturated calcareous sand foundations.

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]

, 2009
In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).
