| Description | The phenomenon oh shear localization in grain skeletons is experimentally well known, but not easily modeled by continuum theories. Here the framework of hypoplasticity is used in combination with a rate-type Cosserat theory. The word polarization denotes the appearance of polar stress components which is characteristic of shear localization. It can be forced by shearing along a rough wall (compared with the grain size), calling for a boundary layer or interface theory. It can be spontaneous somewhere inside the granular body without polar quantities at the beginning. It is intended to explain and estimate the two cases in a simple and realistic manner. The considerations are focused upon plane strain shearing of an infinite strip. Book Name: Bifurcation and Localisation Theory in Geomechanics |
