Record #118794:

Pressure of crushed ice as Mohr-Coulomb material against flat, asymmetric indentor / Dat Duthinh.

Title: Pressure of crushed ice as Mohr-Coulomb material against flat, asymmetric indentor / Dat Duthinh.
Author(s): Duthinh, Dat.
Date: 1992.
In: Journal of Cold Regions Engineering. (1992.), Vol. 6(4) (1992)
Abstract: Pressure exerted on axisymmetric indenter by thin layer of crushed (sea) ice modelled as Mohr-Coulomb material is solved approximately, resulting in closed-form solution that is shown to hold for plane strain situations as well. Pressure decreases exponentially from centre to edge, and increases rapidly as layer becomes thinner. At thicknesses less than critical value, other physical processes such as melting and sintering occur and assumption of granular material in central region no longer holds. Viscous fluid model may be more appropriate here.
