Abstract: A material is considered which consists of rough interacting blocks. The interaction, which is expressed in terms of the ratio of the normal and tangential force at the contact points of the ...

Abstract: A granular medium is viewed as a heterogeneous continuum that satisfies mechanical equilibrium at each material point. Analysis of the strain distribution under deviatoric loading displays structures formation when the ...

Abstract: In the technical note, a two-dimensional mathematical model for piping under a dam on a granular material is reported. No details of the calculation are given, but the results are communicated. The key feature of the model ...

Abstract: The flow in a torsional shear cell is investigated with the purpose of finding a measure for the wall effect due to strongly nonuniform flow in the vicinity of the edge of the top platen. ...
