Investigation of the Flow of Natural Ice (Izuchenie Techeniia Estestvennykh L'Dov),
Abstract
Both the speed of deformation (flow) and viscosity of the samples tested depend primarily on the direction of the applied external force relative to the frozen surface, or, more accurately, relative to the direction of the optical axes of the crystals. If flow takes place in a direction parallel to the frozen surface (perpendicular to the optical axis for the majority of crystals), then the viscosity has a minimal value. If force is applied to the ice in a direction perpendicular to the frozen surface, then the fluidity of the ice is significantly less. In any case, the viscosity of the ice in this direction is greater by 10 to 100 times the viscosity of the ice in the direction parallel to the frozen surface.
