Abstract:
Shear band phenomena, as for instance the well-known base failure and slope failure problems of geotechnical engineering, occur as a result of local concentrations of plastic strains in small bands of finite width. The mechanical reason for this behaviour lies in the basic properties of frictional materials, where, in the brittle regime, the plastic dilatation yields local softening effects. However, it is well known that the numerical description of shear band phenomena, e. g. in the framework...     »
