Abstract
THE PROPOSED WORK PROVIDES FOR A DEMONSTRATION OF THE FEASIBILITY OF A NEW TYPE OF FLAT-PLATE STRESS SENSOR FOR OBSERVATION OF SEA-ICE STRESSES. THE SENSOR IS DESIGNED TO MEASURE NORMAL TENSILE AND COMPRESSIVE STRESSES WHILE OVERCOMING THE ACCURACY LIMITATIONS OF EXISTING ICE STRESS MEASUREMENT TECHNIQUES. A FIBER-OPTIC TECHNIQUE IS USED TO OBSERVE STRESS. THIS TECHNIQUE PROVIDES A SIMPLE, LOWPOWER ICE STRESS MEASUREMENT TECHNIQUE SUITABLE FOR REMOTE DEPLOYMENT AS PART OF A LONG-TERM PROGRAM FOR MONITORING ARCTIC ENVIRONMENTAL PARAMETERS. THE FEASIBILITY DEMONSTRATION INCLUDES NUMERICAL AND EXPERIMENTAL EVALUATIONS OF THE PRECISION AND ACCURACY OF THE SENSOR RESPONSE UNDER VARYING CONDITIONS OF TEMPERATURE, TRANSVERSE LOADING, SHEAR LOADING AND ICE MODULUS.
