Preliminary measurements of terminal crack velocity in ice

Direct measurements of ice crack velocity obtained from double cantilever beam fracture toughness specimens gave a terminal velocity of approximately 20 m/s. Fragrant size in ice is not the result of bifurcation but a consequence of the various stress fields developed. Peer reviewed: Yes NRC publica...
