Mechanism and effects of snow accumulations and controls by lightweight snow fences [PDF]

open access: yesJournal of Modern Transportation, 2016
This paper investigates the snowdrifts caused by lightweight fences along the lines on the flatland through the computational fluid dynamics method. The characteristic ambient flows around the solid fences and the porous fences with varied heights and bottom wind gaps are simulated in the numerical model, and the working mechanism of “interception” and

Stress measurements in the weak layer during snow stability tests

open access: yesAnnals of Glaciology
The snow compression test is a snow stability test where an isolated column of snow is progressively loaded by tapping on it to induce failure in a possible weak layer.

Microstructure-based modeling of snow mechanics: a discrete element approach [PDF]

open access: yesThe Cryosphere, 2015
Rapid and large deformations of snow are mainly controlled by grain rearrangements, which occur through the failure of cohesive bonds and the creation of new contacts. We exploit a granular description of snow to develop a discrete element model based on

Asteroid flux towards circumprimary habitable zones in binary star systems: I. Statistical Overview

open access: yes, 2015
So far, multiple stellar systems harbor more than 130 extra solar planets. Dynamical simulations show that the outcome of planetary formation process can lead to various planetary architecture (i.e.

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Wet Granular Materials

open access: yes, 2006
Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many ...

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Viscoelastic analysis of stress waves through cohesive snow in layered and 2D configurations

open access: yesJournal of Glaciology
Dynamic surface loads generate stress waves in snow that can trigger slab avalanches. Previously, we determined Maxwell-viscoelastic model parameters from one-dimensional, homogeneous laboratory experiments resembling Compression Tests (CTs).

Estimating the effective elastic modulus and specific fracture energy of snowpack layers from field experiments

open access: yesJournal of Glaciology, 2016
Measurements of the mechanical properties of snow are essential for improving our understanding and the prediction of snow failure and hence avalanche release. We performed fracture mechanical experiments in which a crack was initiated by a saw in a weak

Truth : a concept unlike any other [PDF]

open access: yes, 2021
This paper explores the nature of the concept of truth. It does not offer an analysis or definition of truth, or an account of how it relates to other concepts.
