چکیده

Abstract The slipperiness of ice is well known while, for skating, its mechanism still needs further investigation, where the complex interactions including thermal conduction skate—meltwater—ice system, ploughing and frictional melting to friction force are unclear. This study presents a theoretical framework simplified analytical solution unveil when curved skate sliding on ice. theory validated by experiments effects these various factors, velocity, temperature, supporting weight, geometry blade revealed in detail. finds that contribution from deformation through indentation fluid shear motion meltwater layer comparable with each other, which thus clarifies how substrate together regulates during skating.

Ice friction in speed skating: can klapskates reduce ice frictional loss?

PURPOSE Reducing ice friction was one of the motives for developing the klapskate. However, the magnitude of power dissipation that occurs with conventional skates when a skater plantar flexes his ankle and the tip of the blade is pressed into the ice has not been quantified previously. In this study, we examine how ice friction varies during a single stroke with conventional skates and estimat...

How ice shelf morphology controls basal melting

[1] The response of ice shelf basal melting to climate is a function of ocean temperature, circulation, and mixing in the open ocean and the coupling of this external forcing to the sub–ice shelf circulation. Because slope strongly influences the properties of buoyancy-driven flow near the ice shelf base, ice shelf morphology plays a critical role in linking external, subsurface heat sources to...

Peak effect versus skating in high-temperature nanofriction.

The physics of sliding nanofriction at high temperature near the substrate melting point, TM, is so far unexplored. We conducted simulations of hard tips sliding on a prototype non-melting surface, NaCl(100), revealing two distinct and opposite phenomena for ploughing and for grazing friction in this regime. We found a frictional drop close to TM for deep ploughing and wear, but on the contrary...

Fault rheology beyond frictional melting.

During earthquakes, comminution and frictional heating both contribute to the dissipation of stored energy. With sufficient dissipative heating, melting processes can ensue, yielding the production of frictional melts or "pseudotachylytes." It is commonly assumed that the Newtonian viscosities of such melts control subsequent fault slip resistance. Rock melts, however, are viscoelastic bodies, ...

Ice skating promotes postural control in children.

High fall rates causing injury and enormous financial costs are reported for children. However, only few studies investigated the effects of balance training in children and these studies did not find enhanced balance performance in postural (transfer) tests. Consequently, it was previously speculated that classical balance training might not be stimulating enough for children to adequately per...
