Factors Influencing the Coeffecient of Friction Between Sea Ice and Various Materials

Abstract

Coefficient of friction test between sea ice and various construction materials were conducted to clarify the ice-material interaction. This ice-material properties are necessary to calculate the ice forces on sloping structures in cold coastal and offshore regions. Through the six years experimental studies, the following conclusions have been drawn (Saeki et al. 1986) The coefficient of friction have been found to be affected by the following: i) relative velocity; ii) sea ice temperature; and iii) surface roughness of construction materials. They have been found to be relatively unaffected by the following; iv) contact area; v) normal stress; vi) growth direction of sea ice; and vii) water at the sea ice-material interface.
