Undrained Response of Granular Soil Involving Localized Deformation

In this paper an attempt is made to provide a macroscopic description of undrained deformation, in saturated granular materials, in the presence of a shear band. First, the case when both constituents (i.e., the intact and shear band material) respond in an undrained manner is considered. Subsequently, the problem is reformulated by allowing for an exchange of water (partial drainage) in constituents due to a rapid dissipation of the excess …
