Abstract
The theoretical basis and practical implementation of a complex loading device with instrumentation for mechanical properties of granular medium are described in the article. Thereupon, the procedure to determine the deviation from coaxiality of stress and strain tensors is developed. The authors report test data obtained on sand of various grain size. It has been found that rotation of strain tensor axes outruns rotation of stress tensor axes by an approximate angle of 21°.
