Abstract
Field experiments on cylindrical and prismoidal specimens oriented in the plane of the ice cover and perpendicular to it are reported. Nominal strain rate was varied from 2 x 10[-5] s[-1] to 5 x 10[-4] s[-1]; both load and strain were monitored continuously. The strength of vertical specimens of unaligned columnar-grained ice was about three times that of horizontal specimens. Both orientations showed similar increase in strength with increasing strain rate. On the other hand, strain at yield for both specimen orientations was similar and showed no dependence on strain rate. Test system stiffness was measured and a technique for predicting strains is described. The measured uniaxial strength results are used to predict strength under the confined loading condition.
