Mechanized transport for snow surveying
Eos, Transactions American Geophysical Union, 1946This paper gives the reasons for increased interest in mechanizedtravel on snow, lists 12 characteristics to be noted in the performance of such a machine, and describes a series of field tests of a particular make of snow vehicle. This vehicle, which is described, met the requirements for performance.

Development of the snow dragging mechanism for an autonomous snow eater robot
2010 IEEE/SICE International Symposium on System Integration, 2010The development of one part of the autonomous robot specialized in the snow removal task is presented in this paper. With a small size and light weight this robot will be a helpful partner in winter season. This study is focused in the dragging mechanism of the snow eater robot.

Mechanical analysis of the seasonal snow cover
Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000Abstract A snow model has been developed to calculate the forces and displacements of a seasonal snow cover in order to obtain information on damage caused by snow to forestry plants and technological constructions. Two components of motion may be observed in a settled snowpack: creeping (internal deformation), depending on the internal body weight ...

Mechanics of the Turning Snow Ski
1985A snow ski turning at a constant radius and a constant speed is analyzed through a model of the skier/snow/ski dynamic system. The skier is modeled as a rigid body pivoted at the ski; the cutting properties of the snow are empirically modeled from ice cutting data; the ski is represented as a Euler-Bernoulli beam.

On the mechanics of snow slab release
Cold Regions Science and Technology, 1990Abstract The mechanics of snow slab release is considered from the viewpoint of mechanics of continua. Its result shows that snow cannot fracture until a critical strain rate and a critical fracture strain is reached in a weak layer of the snowpack.

Review Mechanical properties of ice and snow
Journal of Materials Science, 2003The mechanical properties of ice and snow are reviewed. The tensile strength of ice varies from 0.7–3.1 MPa and the compressive strength varies from 5–25 MPa over the temperature range −10°C to −20°C. The ice compressive strength increases with decreasing temperature and increasing strain rate, but ice tensile strength is relatively insensitive to ...

Mechanisms of Snow Mold Resistance in Wheat
2013Snow molds can limit production of winter wheat in regions that are prone to deep persistent snow during the winter. There are two mechanisms involved in resistance to snow molds: (1) genetic resistance varieties and (2) age-related resistance varieties.
