✦ Synopsis

A #ow theory describing the yielding of anisotropic frictional materials is discussed. The formulation incorporates directional distribution of voids as a measure of the material microstructure. The conditions at failure are de"ned by invoking a set of scalar-valued functions representing spatial variation of the basic material parameters. The #ow rule is generalized to incorporate the e!ect of the initial fabric of the material. The formulation is illustrated by some numerical examples demonstrating the directional dependence of the load-deformation characteristics.
