Force-controlled shear experiments with snow samples

  title={Force-controlled shear experiments with snow samples},
  author={Ingrid Reiweger and Robert Ernst and J{\"u}rg Schweizer and J. Dual},
Natural dry-snow slab avalanches start with a failure within a weak snow layer. In order to understand the mechanical behaviour and the failure mechanism, we performed loading experiments with homogeneous and layered snow samples under controlled conditions in a cold laboratory. For simulating loading conditions similar to the natural snow pack, we designed and built an apparatus where a snow sample can be tilted by a ‘slope angle’ and is loaded via the gravitational force. The deformation… CONTINUE READING
