Abstract : Cyclic loading fatigue tests have been performed on freshwater ice subjected to reversed bending. A technique has been developed to take replicas of the fracture surfaces, which have been examined to measure porosity and to seek evidence of cyclic crack growth. Some striations have been found, but the relative contributions of plastic deformation and cleavage mechanisms remain unclear. Further investigation is needed to see if cracks grow immediately on cyclic stressing from existing defects or if there is a significant initiation period. A dependence of fatigue life on porosity, applied strain range and temperature has been demonstrated.
