abstract Formation of shear band during triaxial compression test of a sample of granular material was investigated experimentally. A new method of displacement field fixation in the sample of granular material was proposed. The method allows to analyse of displacement distribution inside a sample of any course granular material. Thickness of the fully developed shear band obtained in the triaxial compression test of a mustard seed was found approximately 15 times bigger than the mean seed diameter.
