Proportional straining experiments have been performed on columnar-grained S2 fresh- water ice biaxially compressed across the columns at –108C at a strain rate of (4.5 ???? 1.5) ???? 10–3 s–1. The results are compared with those obtained earlier (Iliescu and Schulson, 2004) from the same kind of ma...
