Fracture toughness of snow in tension

Fracture toughness of snow in tension

Notched cantilever beams of snow were broken under their own weight to determine the fracture toughness of snow with densities between 100kgm −3 and 540 kgm −3 . It varies with the relative density according to K lc = 7.84 (ρ snow /ρ ice ) 2.3 kPam ½ . Snow in tension is one of the most brittle mate...

Zusammenfassung:Notched cantilever beams of snow were broken under their own weight to determine the fracture toughness of snow with densities between 100kgm −3 and 540 kgm −3 . It varies with the relative density according to K lc = 7.84 (ρ snow /ρ ice ) 2.3 kPam ½ . Snow in tension is one of the most brittle materials known to man.
