Abstract: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.

Title:Materialni parametri za numerično simulacijo postopka stiskanja sintranih dvovišnskih zobnikov
Abstract:V članku so predstavljeni začetni materialni parametri za aluminijev prah Ecka Alumix 231, ki so potrebni za uspešno izvedbo numerične simulacije stiskanja sintranih komponent s primerno programsko opremo. S porušitvenimi preizkusi in pridobljenimi eksperimentalnimi rezultati je bilo mogoče določiti potrebne parametre materiala z Drucker-Prager-jevim cap (DPC) modelom, ki določajo linearno območje DPC modela v grafu ekvivalentne tlačne obremenitve v odvisnosti od deviatorične obremenitve. Uporabljeni so bili cilindrični preizkušanci (zelenci), ki so bili stisnjeni z mehansko stiskalnico in kasneje obremenjeni do porušitve v osni in radialni smeri.
