Opis: This paper presents the initial material parameters for the Ecka Alumix 231 aluminum-powdered metal required for a successful numerical simulation of a compaction process for sintered components with a proper software package. Experimental work was used to obtain Drucker-Prager-cap (DPC) model material parameters with the help of a Brazilian disc test and a uniaxial compression test for the linear part of the DPC model in the equivalent pressure stress/deviatoric stress (p-q) plane. The specimens used for this test were cylindrical probes (greens) that were compacted with a mechanical press and then compressed to the failure point in the axial and radial directions.Ključne besede: aluminum-based powder, compaction process, Drucker-Prager cap model, numerical simulation, Ecka Alumix 231Objavljeno v DKUM: 16.03.2017; Ogledov: 1569; Prenosov: 426 Celotno besedilo (864,37 KB)Gradivo ima več datotek!
