Modeling Wet-Snow Shedding from Current-Carrying Conductors [PDF]
The initiation of wet-snow shedding from currentcarrying conductors was studied experimentally and theoretically. A suspended cable with cylindrical snow accretion was considered, and some of the snow properties at the end of sleeve were measured and ...

On the compressive strength of weak snow layers of depth hoar
Journal of GlaciologyWe determined the compressive strength of weak layers of faceted crystals and depth hoar using artificially grown samples with a wide range of microstructural morphologies in a cold laboratory setup.

Numerical study of fracture arrest on snow cover [PDF]
Fracture and Structural Integrity, 2010 Under the hypothesis of a perfectly brittle phenomenon, avalanche triggering can be investigated numerically by means of Linear Elastic Fracture Mechanics (LEFM).

Ice Spheres as Model Snow: Tumbling, Sintering, and Mechanical Tests
Frontiers in Earth Science, 2019 The snow microstructure is crucial for the mechanical behavior of snow, but is usually simplified in numerical models. In Discrete Element Models (DEM), often used in snow mechanics, the microstructure is typically represented by sphere assemblies.

Fuzzy modelling of powder snow avalanches [PDF]
, 2004 This paper examines powder snow avalanches by introducing a predetermined degree of variation, or fuzziness, in model parameters. Given a value of vagueness in the parameters, fuzzy set theory makes it possible to evaluate the vagueness in the results ...

Experimental Simulation of Wet-Snow Shedding from Sagged Cables [PDF]
The process of wet-snow shedding from overhead cables was simulated in cold-chamber experiments under different ambient conditions. The main objective of the study was to examine how cable sag influences the snow-shedding process. However, the effects of

The mechanics of snow friction as revealed by micro-scale interface observations
Journal of Glaciology, 2018 The mechanics of snow friction are central to competitive skiing, safe winter driving and efficient polar sleds. For nearly 80 years, prevailing theory has postulated that self-lubrication accounts for low kinetic friction on snow: dry-contact sliding ...

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]
, 2015 During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.
