| Title: | The effects of end conditions on the strength and fracture of ice under compression / G.J. Lasonde, M.C. Gies, E.M. Schulson. |
| Author(s): | Lasonde, G. J. Gies, M. C. Schulson, E. M. |
| Date: | 1988. |
| Publisher: | [Delft]: International Association for Hydraulic Research, Committee on Ice Problems |
| In: | Proceedings, the 9th International Symposium on Ice, 23-27 August 1988, Sapporo, Japan. (1988.), Vol. 1. |
| Abstract: | Experiments at -10°C established that end conditions/platens affect both brittle compressive fracture strength of granular ice measured at 10⁻³ s⁻¹ and fracture mode, but have little or no effect on ductile or peak compressive strength measured at 10⁻⁵ s⁻¹. Specifically, radial confinement raises fracture strength by about 10% and induces shear faulting, whereas radial expansion lowers strength by about 10% and induces axial splitting. Variations in strength are relative to measurements obtained using radially compliant brush platens which also induce splitting. Similar effects occur in stronger columnar, fresh-water ice loaded along columns, and are independent of length to diameter ratio from 2.5 to 1.3. |
