On the proper characterization of tooling motions and initial conditions in powder die compaction modeling

The present paper is concerned with the finite element modeling of Powder Metallurgy (P/M) cold die compaction process. Rather than on material constitutive theories or on numerical algorithmic issues, attention is confined exclusively on an scarcely addressed issue in the P/M modeling literature: t...

The authors wish to thank also AMES S.A. for supporting the experimental part of this research; a special debt of gratitude is owed to Enric Sánchez and Josep Lluis Celeiro for their endless patience in helping us navigate the intricacies of CNC press machines.Peer Reviewed20112011-08-0120202020-07-03journal articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/192418https://dx.doi.org/10.1016/j.jmatprotec.2011.03.006reponame:UPCommons.
