Measurement of Ice Forces and Interfacial Pressure during Medium-Scale Indentation Tests In Japan

Use of tactile sensors during small-scale and medium-scale indentation tests has produced data on interfacial pressure generated during ice-structure interaction. These data have revealed information on the ductile and brittle crushing processes that are active during low and high indentation rates, respectively. In this paper, the authors make use of the force measurements to calibrate the tactile sensors at one instant of a force record. After comparing forces obtained from tactile sensors with those measured by load cells, the authors present data on average contact interfacial pressure as well as effective pressure during brittle crushing of ice. The authors compare the effective pressure measured during these tests with those measured during small-scale indentation tests and full-scale measurements of ice forces on the Molikpaq structure.
