Dynamic models for impact-initiated stress waves through snow columns

Journal of Glaciology
The objective of this research is to model snow's response to dynamic, impact loading. Two constitutive relationships are considered: elastic and Maxwell-viscoelastic.

On how avalanches penetrate the SOL and broaden heat loads

Nuclear Fusion
Recent experiments reported a correlation between power law core temperature spectra and D _α emission, suggesting that heat avalanches penetrate the SOL.

[Avalanche accidents and treatment of avalanche victims].

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2016
Avalanches may be provoked spontaneously or as a result of human activity, and they trigger the need for considerable rescue resources. Avalanche search and rescue operations are complex and characterised by physical and mental stress. The guidelines for resuscitation of avalanche victims may be perceived as complex and abstruse, which can lead to ...

Recherches françaises dans le domaine des avalanches : les sites expérimentaux

, 2004
This paper contains a short description of the experimental Lautaret site dedicated to avalanche dynamic studies. Since the seventies, many experimental campaigns allowed measuring different avalanche parameters such as velocity, height and pressure ...

A bcc refractory high-entropy alloy: the ideal case of smooth plastic flow

Materials Research Letters
Single crystalline metals exhibit correlated dislocation dynamics, irrespective of lattice system. This collective evolution of dislocation structures is intermittent and scale-free, implying divergent length scales that play a critical role in failure ...

Meteorological conditions and avalanche danger of winters in the Caucasus at the end of the 21^st century based on the results of CMIP6 models

Лëд и снег
The paper considers a forecast of avalanche danger in the Caucasus at the end of the 21st century based on the climatic avalanche indicator criterion developed at Moscow State University, using the results of the CMIP6 Earth System Models (ESM).
