ABSTRACT
Shear bands were observed in the granular layers of deformed specimens composed of alternating layers of granular and cohesive materials. Several purely granular specimens were prepared and deformed in a specially designed apparatus in order to observe shear band formation. During deformation, visible shear bands could be seen forming in the specimens, as documented in the included digitized video. Three categories, primary, secondary and tertiary, shear bands were identified. The names are based on the orientation and development location of the shear bands.
