A laboratory test program was conducted to measure the deformation and strength properties of multi-year ice at temperatures of -2, -10 and -20 degrees C. A penetration model based on contact coefficients as suggested by Varsta was formulated to physically describe the penetration process. Un programme d'essais en laboratoire a été mené pour mesurer la déformation et la résistance de la glace de plusiers années à des températures de -2, -10 et -20 degrés C. Un modèle de pénétration basé sur des coefficients de contact proposés par Varsta a été formulé pour décrire physiquement le processus de pénétration. Peer reviewed: Yes NRC publication: Yes
