Abstract: | In the paper results from ice indentation tests are described. The tests were carried out to clarify the failure process of ice and also the loads caused by indentation into ice. The test results showed for the first time the nature of the brittle ice failure in caused a narrow high pressure zone (a line-like feature) transmitting the high pressures. The test results are described in some detail.
After looking at the test results, the implications on modeling ice failure are discussed. Especially the results of more recent tests are discussed and a phenomenological model for ice failure is given. |
