Record #112508:

The effect of confinement on the brittle compressive fracture of ice / E.M. Schulson, D.E. Jones, G.A. Kuehn.

Title: The effect of confinement on the brittle compressive fracture of ice / E.M. Schulson, D.E. Jones, G.A. Kuehn.
Author(s): Schulson, E. M.
Jones, D. E.
Kuehn, G. A.
Date: 1991.
In: Annals of Glaciology. (1991.), Vol. 15 (1991)
Abstract: Presents preliminary results from experiments carried out at -40°C on granular fresh-water ice confined through proportional loading. Reveals two distinct regimes of behaviour: at lower confinement, fracture stress increases markedly as degree of confinement increases, wheres, at higher confinement, fracture stress increases less sharply. Wing cracks seen in ice within low degree of confinement. Data are analyzed in terms of frictional crack sliding-wing crack mechanism of brittle compressive fracture.
