... to the data obtained by authors. The width of the structure (W), ice thickness (h), indentation velocity (V) and urn-axial compressive strength (oc) are the major factors, and the choice of ice load equation to satisfy our Medium- Scale-Field-Indentation data depends on the value of (V/h).

... ABSTRACT Field indentation tests using medium-scale model structures have been conducted since the winter of 1996. In the winter 1998 tests, 1.5m-wide model structures were used" indentation velocity, 0.03 to 3cm/sec, and sea ice, up to 24cm thick. Two-dimensional pressure-sensing panels were...

.../structure interactions. The tests consisted of ice indentation tests, tests on physical properties of ice sheets, and measurements of ice sheet deformation. This paper describes for three indentation velocities, the relation between ice sheet strain area and ice failure modes due to ice/structure...

The tests were perlbrmed varying the indentation velocity, compliance of the indentor...

... ABSTRACT Field indentation tests were conducted on sea ice at a harbor on Lake Notoro, Hokkaido, Japan, with a model structure width of 0.6 to 6.0m, an ice thickness up to 0.5m and an indentation velocity of 0.3 to 30mm/sec. In order to conduct large scale indentation tests in the field...
