| Abstract | Five blocks of ice, representing four medium scale indentation tests were examined. These blocks represent the following April 1989 tests: (1) Test 4, Block 1; (2) Test 4; Block 2; (3) Test 6 and 7; (4) Test 8; and (5) Test 10. The analyses were made using double-microtomed thin-sections and observing them under polarised light and combined polarised/scattered light technique. It is shown that the latter method is a powerful tool for the examinations of deformed and undeformed ice. Macro-crack damages, micro-crack damages and inclusions are revealed in a dramatic manner by the combined polarised/scattered light technique. Apparently undamaged ice, that was visible as 'blue zones' immediately after the indentation tests, are shown to have undergone severe microstructural modifications. |
