Snow fracture in relation to slab avalanche release: critical state for the onset of crack propagation

Johan Alexandre Philippe Gaume, Nander Wever, Jürg Schweizer, Alec van Herwijnen

The failure of a weak snow layer buried below cohesive slab layers is a necessary, but insufficient, condition for the release of a dry-snow slab avalanche. The size of the crack in the weak layer must also exceed a critical length to propagate across a sl ...

Crack propagation speeds in weak snowpack layers

Johan Alexandre Philippe Gaume, Jürg Schweizer, Bertil Trottet, Grégoire Bobillier, Alec van Herwijnen

For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred in ...

Micro-mechanical insights into the dynamics of crack propagation in snow fracture experiments

Johan Alexandre Philippe Gaume, Jürg Schweizer, Grégoire Bobillier, Alec van Herwijnen

Dry-snow slab avalanches result from crack propagation in a highly porous weak layer buried within a stratified and metastable snowpack. While our understanding of slab avalanche mechanisms improved with recent experimental and numerical advances, fundamen ...
