摘要：
The compaction response has been investigated for an array of spherical particles composed of elastic, perfectly plastic material. Numerical simulations have been used to examine the evolution of contact size, contact pressure and macroscopic yield surface with the degree of compaction. It is found that the macroscopic yield surface of a compact has a corner at the loading point, and its shape evolves with increasing strain in a non self-similar fashion.
