Title: Fracture of Layered Snow by Cohesive Zone Technique and Experiments: Date: 2004; Authors: S. Senthil, P. Mahajan, S.K. Joshi; Description: One mechanism responsible for avalanche initiation is the weak bond between snow layers. Experiments under controlled conditions at the cold lab are ...; Object ID: issw-2004-064.pdf; Keywords: fracture, snow layers, cohesive zone, fem; View additional details about Fracture of Layered Snow by Cohesive Zone Technique and Experiments

Title: Fracture Character in Compression Tests: Date: 2004; Authors: Alec van Herwijnen, Bruce Jamieson; Description: Stability tests are widely used to identify and qualify potential failure layers for slab avalanches. As an addition to stability test scores, some av...; Object ID: issw-2004-182-191.pdf; Keywords: stability test, avalanche forecasting, fracture initiation, fracture propagation, stability evaluation; View additional details about Fracture Character in Compression Tests

Title: Fracture Toughness for Dry Slab Avalanches: Date: 2002; Authors: David M. McClung; Description: Dry slab avalanches release by propagating shear fractures. Since alpine snow is a quasi-brittle strain softening material, it is implied that fractur...; Object ID: issw-2002-304-306.pdf; Keywords: fracture, dry slab avalanche; View additional details about Fracture Toughness for Dry Slab Avalanches

Title: Effects of an Early Season Rain Crust on Snow Pack Stability within the Continental Climate: Date: 2002; Authors: Dan Moroz; Description: On January 6th and 7th, 2002, the central and northern mountains of Colorado, and Copper Mountain ski resort, experienced a "freezing rain" weather e...; Object ID: issw-2002-502-507.pdf; Keywords: fracture, stability, snowpack, climate; View additional details about Effects of an Early Season Rain Crust on Snow Pack Stability within the Continental Climate

Title: Interpreting Fracture Character in Stability Tests: Date: 2002; Authors: Alec van Herwijnen, Bruce Jamieson; Description: For at least a decade or two, some avalanche safety programs have recorded and interpreted the character of fractures in stability tests. It has been ...; Object ID: issw-2002-514-520.pdf; Keywords: snow stability tests, snow fracture, snow layer, avalanche forecasting; View additional details about Interpreting Fracture Character in Stability Tests

Title: Theoretical Snowpack Behavior Associated With Postcontrol Avalanches: Date: 1982; Authors: Thomas E. Pratt; Description: Postcontrol avalanches are commonly associated with two conditions: (l) inability of explosives to produce slope failure even though unstable conditi...; Object ID: issw-1982-023-024.pdf; Keywords: triggering, slope release, postcontrol, creep rate; View additional details about Theoretical Snowpack Behavior Associated With Postcontrol Avalanches

Title: A Plastic Wave in Snow: Date: 1982; Authors: Atsushi Sato; Description: When snow is pushed very fast by a moving body, not only an elastic wave but also a plastic wave is generated at the head of the body. Though an elast...; Object ID: issw-1982-024.pdf; Keywords: plastic wave, elastic wave, denstiy; View additional details about A Plastic Wave in Snow

Title: Release and Motion of Arctic Slushflows: Date: 1982; Authors: Arthur Mears; Description: Two types of slushflows studied during the spring of 1981 and 1982 in the Philip Smith Mountains, central Brooks Range, Alaska, were (l) point failur...; Object ID: issw-1982-003-004.pdf; Keywords: slushflow, runoff,; View additional details about Release and Motion of Arctic Slushflows

Title: Discussion of Deformation Measurements in Relation to Snow Slab Release: Date: 1976; Authors: D.M. McClung; Description: Snow stratigraphy studies at avalanche fracture lines indicate that the situation may be viewed essentially as a thick slab overlying a thin failure p...; Object ID: issw-1976-186-192.pdf; Keywords: snow stratigraphy, slab release, fracture lines; View additional details about Discussion of Deformation Measurements in Relation to Snow Slab Release
