Stress-strain relations in snow under uniaxial compression
Landauer, J. K. (Joseph K.)
Research ReportSummary: Laboratory tests on the uniaxial compression of snow were conducted at constant specific velocity, and creep tests at constant load. The dependence of uniaxial deformation on stress increases from a linear relationship at low stress to approximately a cubic relationship at approximately 1 kg./cm^2. The temperature dependence indicated in the creep tests leads to a value for the activation energy of about 14,000 cal./mole. Significant deviations in the relations were observed, however, and greater reproducibility is necessary if more fundamental relationships are to be found.
