Abstract
An extensive numerical campaign of particle mechanics calculations that predict microstructure formation and evolution during die compaction, up to solid fractions close to one, of monodisperse plastic spheres that exhibit power-law plastic hardening behavior is presented. The study is focused on elucidating the relationship between particle plastic properties, loading conditions, and statistical features of the resulting microstructure. This communication provides fundamental insight into the achievable space of microstructures through die compaction, for given plastic stiffness and hardening exponent at the particle scale.

Bibliographical note
Funding Information:The motivation for this work arose from a special topics course for undergraduate students, ME479, on microstructure evolution of granular systems given as an independent research project from the spring of 2014 to the spring of 2017 at the School of Mechanical Engineering at Purdue University. Participants were Kiran Balakrishnan (Spring 2014), Jili Liu (Summer 2014 to Fall 2014) and Alex Thomas (Spring 2016 to Spring 2017). The authors gratefully acknowledge the support received from the National Science Foundation grant number CMMI-1538861, from Purdue University’s startup funds, and from the Network for Computational Nanotechnology (NCN).
