TECHNIQUES FOR MEASURING STRESS IN SEA ICE

This report describes two techniques for measuring stress in situ in sea ice sheets. A technique using embedded load cells has been found successful in measuring compressive creep or failure stresses as well as moderate tensile stresses. A stress relief technique has been investigated and found unsuccessful. Design details are presented on transducers for each technique and cold-hardy instrumentation is discussed. A technique using inflated air bags to produce known stress fields is presented.
