| Title: | The indentation and arrest stress intensity factors of first year columnar sea ice / B.L. Parsons, J.B. Snellen, D.B. Muggeridge. |

| Abstract: | Samples collected from Allen Bay, near Resolute Bay, NWT, Canada, in April 1987. Initiation stress intensity factor was found to increase with decreasing loading rate, but arrest stress intensity factor is time-independent. Crack growth length depends on drop from initiation to arrest value during event but showed no dependence on load rate. Arrest was observed in brine drainage channels and not at grain boundaries. Results show that arrest stress intensity factor should be used in crack length predictions during indentation phenomena, not critical stress intensity factor. Crack growth in ice is unstable, dynamic, and supplies significant kinetic energy to ice. |
