Abstract

The adhesion strength of ice to other materials has been studied both experimentally and theoretically. In the experimental part the adhesion strength of ice to polyethylene (PE), polyvinylchloride (PVC) and steel was measured varying the temperature, the strain rate, the ice thickness and the salinity of the ice. The tests were made with platelike specimens having columnar-grain ice on both sides. The adhesion strength proved to depend strongly on the salinity of the ice. In the theoretical part a method for calculating the adhesion strength has been presented. The method is based on fracture mechanics, and it can be applied to both fresh-water ice and saline ice. It has been shown that in saline ice the effect of salinity can be described by the relative brine volume. The mathematical model satisfactorily explains also e.g. the effect of strain rate, when a time-dependent elastic modulus of ice is used. There seems to be a general agreement between the calculated results and the experimental data obtained by several workers, but there are also some exceptions. The calculation method is applied also to the shear and tensile strengths of saline ice; the agreement with experimental results is satisfactory.
