A Mechanical Test Procedure for Avalanche Snow
Abstract The design, construction, and testing of a portable constant strain-rate testing machine for determining the mechanical behavior of avalanche snow is described. The machine is intended for use in determining the stress strain time behavior of low-density natural snows in the field. A techni...

Summary: | Abstract The design, construction, and testing of a portable constant strain-rate testing machine for determining the mechanical behavior of avalanche snow is described. The machine is intended for use in determining the stress strain time behavior of low-density natural snows in the field. A technique for making direct measurements of strain in the snow sample is described and stress-strain curves are presented for strain-rates ranging from 0.5 to 5.0 x 10 -5 s -1 . The densities of the snow samples tested range from 186 to 335 kg m -3 Ultimate-strength data and relaxation curves arc also presented. |
