摘要
A model for dynamic deformations of granular materials which allows for the localization of flow and the consequent development of shear bands is considered here. Solutions, asymptotic in small time, of Riemann initial-value problems in one space dimension that include a shear band were constructed. The overall structure of the solution is that the material unloads elastically between the shear band and a free boundary that propagates into a region of plastic deformation.
