Title: Wet-Snow Fracture Propagation: Date: 2016-10-02; Authors: Ingrid Reiweger, Markus ZÃ¶chling, Martin Forster, Thomas Wiesinger, Christoph Mitterer; Description: Fracture propagation within wet snow is a key issue in order to understand and predict wet-snow slab avalanches. In our preliminary field study we inv...; Object ID: ISSW16_P1.33.pdf; Keywords: wet snow, fracture propagation, wet-snow avalanches, propagation saw test; View additional details about Wet-Snow Fracture Propagation

Title: Extended Column Test: Repeatability and Comparison to Slope Stability and the Rutschblock: Date: 2016-10-02; Authors: Frank Techel, Matthias Walcher, Kurt Winkler; Description: Information on snow stability is key information when assessing the avalanche situation. However, stability tests like the Extended Column Test (ECT) ...; Object ID: ISSW16_P4.08.pdf; Keywords: extended column test, rutschblock, test repeatability, snow stability, fracture propagation; View additional details about Extended Column Test: Repeatability and Comparison to Slope Stability and the Rutschblock

Title: Slab Avalanche Crown Surface Fractography: Observations and Applications: Date: 2012; Authors: Dave Gauthier; Description: Fractography is the study of the morphological fracture surface features in artificial and natural materials, including bone and rock. Several pattern...; Object ID: issw-2012-115-120.pdf; Keywords: crack propagation, fracture-line, crowns; View additional details about Slab Avalanche Crown Surface Fractography: Observations and Applications

Title: Numerical Modeling of Fracture Propagation in Slabs: Date: 2010; Authors: Chris Borstad, David McClung; Description: We present the results of numerical simulations of tensile failure of snow samples.
