The structure of water in its solid state (ice) is complex. A number of
process parameters and the chemistry of the freezing aqueous solution
influence ice crystal growth and ice characteristics such as crystalline
structure, impurity inclusions, and appearance. The resulting variation
in ice properties makes determining mechanical properties challenging.
This study examines the performance of a Scanning Laser Doppler
Vibrometer (SLDV) used to measure the natural frequency of an ice sample
and consequently evaluate its modulus of elasticity. Analytical and
numerical methods were used, and the results have been compared to
values found in the literature. The modulus of elasticity for the
measured ice plate, with a porosity of 8.8%, was found to be 6.7 GPa,
which is 2.7% lower than previously published values.
