Effect of Fabric on Strain Localization Behaviour of Sands

The pertinence of fabric and dilatancy to the occurrence of strain localization in sand is investigated within the framework of a newly developed microstructure based constitutive model. It is argued that the fabric of sand governs its deformation mode and any subsequent localization into a shear band. Based on the premise that strain localization derives from material instability, the fabric dependent constitutive law is subjected to a …
