     strain localization is a well-known phenomenon in geomaterials. in this process, plastic deformation is observed to concentrate in narrow zones called shear bands. the accurate numerical simulation of the slope stability problems, the bearing capacity of shallow and deep foundations, and the active and passive stresses acting on retaining walls depend strongly on formation of shear bands in granular soils. in this study, an advanced plasticity model formulated within the bounding surface plasticity family and critical state soil mechanics is applied for prediction of strain localization in granular soils. it is shown that realistic predictions are obtained for states at which strain localization can take place.
