LABORATORY DETERMINATION OF DYNAMIC MODULI OF FROZEN SOILS AND OF ICE.
The report presents a summary of results of laboratory investigations of frozen soils and ice to determine the elastic moduli by the dynamic (sonic) method. The elastic moduli were indirectly obtained by measuring the fundamental resonant frequencies of flexural, longitudinal, and torsional vibratio...
