| Résumé | This paper is a follow-up of a previous study on the interaction between upward-breaking conical structures and level ice in a centrifuge. New data were collected from a series of ten ice sheets grown at an inertial acceleration equivalent to 30 times Earth's gravity (30g). A small conical structure was driven against this ice, which ranged in thickness from 5 to 20 mm. Interaction velocities between the structure and the ice were 7,10,40 and 100 mm/s and inertial accelerations were 1 (noram gravity), 30, 60, 80 and 120g. Cones with slopes of 45, 60 and 75 deg. with respect to the horizontal were used. A description of ice rubble build-up against the cone is presented. The horizontal and vertical loads are compared with a prediction algorithm taking into account the 3D nature of the ice loads. The influence of displacement rates is also discussed. |
