Description: Technical Report
Summary: This study establishes a relation between the longitudinal wave velocity and the crushing strength of processed snow at a common density and temperature, provides information on the aging effect of processed snow under controlled temperatures, and shows how sonic measurements can be taken continuously through one sample during the aging process. The study was conducted at Houghton, Michigan, on snow processed by the Peter snow miller and deposited in plywood boxes of 1.5 ft^3. Two sets of samples were obtained, each consisting of 6 boxes of processed snow. A constant-velocity motorized press was used to determine the crushing strengths. The specimens were prepared with a length to diameter ratio of 2.5 to 1, and the measurements were independent of the loading rates. The longitudinal wave velocity was measured with piezo-electric transducers in conjunction with a soniscope, which provided the exciting source and the time-measuring device. A relation between the longitudinal wave velocity and crushing strength at -10°C was established.
