Microcrack nucleation in granular ice under uniaxial compression: effect of grain size and temperature
Uniaxial compression tests were carried out on fresh-water, isotropic, granular ice at a strain rate of 6 x 10-4s-1. We investigated the effect of temperature (between -2 and -39 C) and grain-size (1mm-8mm) on the critical stress and strain at the initial crack nucleation. The amount of non-elastic...

Summary: | Uniaxial compression tests were carried out on fresh-water, isotropic, granular ice at a strain rate of 6 x 10-4s-1. We investigated the effect of temperature (between -2 and -39 C) and grain-size (1mm-8mm) on the critical stress and strain at the initial crack nucleation. The amount of non-elastic strain at this event was estimated. Peer reviewed: Yes NRC publication: Yes |
