Ejection Velocity of Ice Impact Fragments

Icarus, 1995
Abstract Laboratory experiments on the impact disruption of ice were carried out to investigate the collisional phenomena of an icy planet. Ice projectiles were impacted on ice targets at impact velocities of 30 to 530 m/sec, and mass ratios of the projectile to the target of 0.1 to 0.0035.

Crack velocities in freshwater and saline ice

Journal of Geophysical Research: Solid Earth, 1996
This paper presents experimental results on both mode 1 and 2 crack velocities measured in a wide variety of ice types, columnar sea ice, columnar lake ice, laboratory‐grown columnar saline ice, and freshwater columnar and granular ice, in the temperature range from −5° to −35°C.

Ejection velocities of ice fragments in oblique impacts of ice spheres

Advances in Space Research, 1999
Reaccumulation conditions of icy planetesimals in collisional disruption were studied experimentally using a one-stage light gas gun set in a cold room (−18°C). Oblique impacts between ice spheres were used to measure the velocity distributions of fragments. The impact velocities ranged from 170 to 640 m/s, and the projectile-to-target mass ratio was a

Crack Velocity Measurements in Sea Ice

MRS Proceedings, 1994
AbstractTo study crack dynamics in sea ice fast measurements of ice electrical resistance and an electromagnetic emission (EME) from cracks were used. The sample dimensions ranged from 0.05 to 30 meters. In a laboratory grown fresh water ice crack velocities varied from a few hundreds to a thousand meters per second while in the natural sea ice crack ...

Distribution of velocities in an ice-covered stream

Hydrotechnical Construction, 1967
1. An analysis of the uniform motion of fluid in a wide channel, which was carried out by L. K. Nikitin, makes possible the development of a pattern of velocity structure for a stream flowing between two surfaces with different roughness. 2.
