Abstract

The both theoretical and experimental work consists of two parts, the friction of ice and the adhesion strength of ice.Both static and kinetic friction between ice and several materials have been measured varying the temperature, the velocity and the normal load.A method for calculating the coefficient of kinetic friction between ice and some other material has been developed.The method is based on the assumption that the friction is caused by a water film at the contact surface.This water film is produced, when the frictional heat melts ice into water.Combining the equations describing the frictional force and the thermal processes an equation for the coefficient of friction is obtained.The experimental results are not in total agreement with the theory, which shows that also other phenomena than the water film mechanism are involved.The adhesion strength of ice to PE, PVC and steel has been measured varying the temperature, the strain rate, the ice thickness and the salinity of the ice.A method for calculating the adhesion strength has been presented.The method is based on fracture mechanics, and it has been applied to both fresh water ice and saline ice.The mathematical model explains satisfactorily e.g. the effects of strain rate and salinity of ice.
