“…From large (~120 cm × 70 cm × 50 cm) blocks cut from the cover and then transported to and stored at UNIS, we fabricated plate-shaped specimens of dimensions h ~ 45 mm in thickness (parallel to the long axis of the grains), b ~ 100 mm in width and l ~ 600 mm in length. The specimens were equilibrated at −12 °C and then nonreversely loaded across the columns at 0.1 Hz at an outer-fiber stress in the range from ~ 0.1 to ~ 0.7 MPa, using a custom-built 3-point bending rig, Figure 2, attached to a uniaxial loading system termed ‘Knekkis’ (for details on Knekkis see Nanetti and others (2008); Sukhorukov and Marchenko (2014)). The specimens were free from cracks, at least of a size detectable by the unaided eye, but contained a few narrow (< 1 mm dia.)…”

Further to systematic experiments on the flexural strength of laboratory-grown, fresh water ice loaded cyclically, this paper describes results from new experiments of the same kind on lake ice harvested in Svalbard. The experiments were conducted at −12 °C, 0.1 Hz frequency and outer-fiber stress in the range from ~ 0.1 to ~ 0.7 MPa. The results suggest that the flexural strength increases linearly with stress amplitude, similar to the behavior of laboratory-grown ice.

“…Most tests have been conducted within a laboratory setting to quantify the friction responsible for movement over ice. Apart from several uncommon methods such as shear strength, adhesion and stick-slip tests [1]- [4], the most popular ones such as ring-on-disk [1], [5]- [7] or pin-on-disk [8] tests move a material surface repetitively over the same ice path and therefore modify the ice surface with a thin layer of water [6], [9] leading to a departure from an initial ice condition. Sliding over fresh ice has been made possible by moving the sliding object over a spiral path [10].…”

The ability to slide on ice has previously focused on the measurement of friction coefficient rather than the actual sliding velocity that is affected by it. The performance can only be directly measured by the sliding velocity, and therefore the objective was to design and setup a facility to measure velocity, and determine how experimental conditions affect it. Optical sensors were placed on an angled ice track to provide sliding velocity measurements along three sections and the velocity for the total sliding distance. Experimental conditions included the surface roughness, ambient temperature and load. The effect of roughness was best reported with a Criterion of Contact that showed a similar sliding velocity for metal blocks abraded with sand paper smoother than 600 grit. Searching for the effect of temperature, the highest sliding velocity coincided with the previously reported lowest coefficient of ice friction. Load showed the greatest velocity increase at temperatures closer to the ice melting point suggesting that in such conditions metal block overcame friction forces more easily than in solid friction. Further research needs to be conducted on a longer ice track, with larger metal surfaces, heavier loads and higher velocities to determine how laboratory experiments can predict real-life situations.

“…Consequently, varying the experimental parameters it is possible to explore all lubrication regimes, from boundary to hydrodynamic. According to literature the surface roughness has the same importance since it defines the height of the asperities that interact with each other [10,[17][18][19].…”

Over a century of scientific research on the sliding friction of ice has not been enough to develop an exhaustive explanation for the tribological behavior of frozen water. It has been recognized that ice shows different friction regimes, but a detailed description of all the different phenomena and processes occurring at the interface, including the effect of surface roughness of both the ice and the antagonist material is still missing. In this work the effect of surface morphology on the friction of steel/ice interfaces is studied. Different degrees of random roughness on steel surfaces are introduced and the friction coefficient is measured over a wide range of temperature and sliding velocity. Correlation between the surface roughness and the lubrication regime and friction coefficient is discussed. A theoretical model is developed in order to explain this correlation, and to control the tribological behavior of the system by a proper selection of surface roughness parameters.
