This chapter describes micromechanical and macroscopic material models for granular and porous materials and applications to powder technological processing steps. The emphasis lies on powder compaction and sintering, while for the other steps of the process chain (powder fabrication and conditioning, pouring of the loose powder in the die, post-sintering mechanical densification, service behaviour) appropriate models are named and key references are given. The constitutive models.
