DETERMINING THE DYNAMIC PROPERTIES OF SNOW AND ICE BY FORCED VIBRATION.
COLD REGIONS RESEARCH AND ENGINEERING LAB HANOVER N H
Pagination or Media Count:
The complex dynamic Youngs and shear moduli, loss factor and Poissons ratio are presented for naturally compacted glacial snow through a density range of 0.4 to 0.9 gcu cm. A frequency dependence of the moduli and its effect on the computation of Poissons ratio is demonstrated. Considerable scatter is exhibited in the loss factor measurements however, indications are that the loss factors have negligible effect on the modulus computations. Author
