Energy Balance Approach to Shear Band Propagation in Shear-Blade Tests


This paper is an attempt to validate the energy balance approach to modeling of the propagation of a two-dimensional, circular shaped shear band. This shear band can be observed in a shear blade test, performed in the novel shear-blade apparatus. The simplified analytical solution obtained in this paper is based on the fracture mechanics energy balance and the limiting equilibrium approaches. FLAC has been chosen as a standard FD tool to explore and compare numerical with experimental and analytical approaches. Comparison of results from different approaches provides an insight into the complex domain of modeling shear band propagation in soils.
