The paper deals with the effect of grain crushing on shear localization in granular materials in an infinite long narrow granular strip under constant vertical pressure. The calculations were carried out with an enhanced micro-polar hypoplastic constitutive model which is able to describe the salient properties of crushable granular bodies including shear localization. The change of the mean grain diameter with varying pressure was taken into account with the help of formulae from breakage mechanics. The effect of pressure and initial void ratio on shear localization was studied.
