This lecture delves into the mechanics of snow and the dynamics of avalanches, covering topics such as crack propagation, modeling the Propagation Saw Test (PST), elasticity of the slab, propagation speed, slab tensile failure, and friction in slab release. The instructor explains the influence of slab density on crack propagation, the critical crack length, and the factors affecting avalanche release processes. Various stability indices, stress considerations, and the use of Particle Tracking Velocimetry (PTV) are discussed to understand avalanche danger and initiation. The lecture concludes with insights on slab sliding, critical slope angles, and the importance of considering terrain characteristics.
