Работа показывает результаты тестов трехосного сжимания проб зерна ржи. Особенное внимание обратили на процесс подготовки пробы для исследований. Пространственное расположение зерен в пробе описали 2 параметрами: плотностью упаковки и пространственной ориентировкой несферических зерен. В работе исследовали влияние начальной анизотропии пробы зерна ржи (вынужденной пространственной ориентировной зерен) на механические свойства. Результаты представили в виде зависимости отношения напряжений δ₁/δ₃ от угла между направлением ориентировки зерен и системой отнесения.

A series of triaxial compression tests on bulk rye grain was carried out. Because the mechanical characteristics of granular material depend on the spatial arrangement of solid particles and associated voids therefore special attention was paid to the process of sample preparation during the formation of the fabric. Spatial arrangement of particles in a sample can be described by two parameters: packing density and spatial orientation of non-spherical particles. Influence of the initial anisotropy of bulk rye grain (formed by forced spatial orientation of the grains in the sample) on their mechanical characteristics was investigated in this report. Results received were presented as the dependence of δ₁/δ₃ ratio on the angle between long axes of grains and the reference system.
