Notes:
In this paper we present an anisotropic compaction model based on a genericmodeling framework. The model is a generalization of Hill’s anisotropic model tocompressible materials and reduces to a Cam-clay type model in the isotropic limit. Themodel has been calibrated using experimental data for a commercial steel powderobtained from a computer controlled triaxial cell in which the yield surface was probedfollowing loading along different paths in stress and strain space. Closed-formanalytical expressions are presented for the yield surface as a function of the inelasticstrain. The model has been implemented in the general purpose finite element codeABAQUS. Simulations are presented which explore the effect of a detailed structure ofthe constitutive law on the compaction response
