AbstractThe rigidity modulus is determined for simply supported, circular ice plates 0.5 and 1.22 m in diameter. Measurements for the 0.5 m diameter plates were made at -10 deg.C and for the 1.22 m plates in the range of -7 to -37 deg.C. The elastic moduli and Poisson's ratio, calculated from the rigidity modulus, are in the range of 6.0-12.0 GPa and 0.29-0.60 respectively, depending on ice type, temperature, and grain size. The plate characteristic lengths calculated from the measured values of the elastic moduli are compared with characteristic lengths determined from field measurements of the deflection of ice covers under load.
