Abstract

Ice-solid interfaces are of considerable interest in electrical and civil engineering and aviation. Efforts have been made to investigate the strength of ice-solid interfaces in terms of tensile, shear, and impact. This paper examines the fracture energy of ice/metal interfaces, in an attempt to utilize fracture mechanics to characterize the failure of ice/solid adhesion. A four point bending delamination specimen was used to measure the fracture energy of ice/Al and ice/steel joints. The fracture energy of an ice/steel interface was found to be lower than that of an ice/Al interface. The fracture mode was a mixture of cohesive and adhesive failure. The effects of impurities on interface fracture energy was significant.
