Plane-Strain Compressive Strength of Columnar-Grained and Granular-Snow Ice
Abstract An ice cover impinging on a long straight structure is assumed to be under a condition of plane strain. A technique is described for performing plane-strain compression tests, and results are presented for the strain-rate dependence of strength. The plane-strain compressive strength of ice...
