Description

This lecture covers crack propagation in snow mechanics, focusing on modeling the Propagation Saw Test (PST) and its implementation in SNOWPACK. It discusses stress redistributions, critical crack length, elasticity of the slab, snow anisotropy, and friction-induced slab release. The instructor explains the factors influencing slab tensile failure, such as slab density, and the critical slope angle for avalanche release. The lecture concludes with the dynamic phase of crack propagation, slab fracture, and the importance of understanding avalanche danger through stability indices and critical crack lengths.
