| Abstract | Measurements of the fatigue characteristics of sea ice will give an indication of its possible failure mechanisms under repeated loading such as occur with wave action and the operations of vehicles and aircraft. In this paper we present the results of a series of fatigue experiments carried out in the McMurdo Sound, Antarctica during the summer of 1992. The results presented here are in the form of a standard fatigue curve (with zero mean stress), that is "stress amplitude" versus "number of cycles to failure", commonly known as an S-N curve. The "endurance limit", that is the stress below which the sea-ice can withstand an unlimited number of cycles, is for sea ice in situ, approximately half the failure stress. |
