Abstract
Poznavanje materialnih lastnosti je v inženirstvu ključnega pomena. V kombinaciji s funkcijskimi predpisi, ki popisujejo obnašanje materialov pod določenimi učinki, lahko pravilno načrtujemo odzive obravnavanih strojniških problemov. V okviru zaključne naloge smo obravnavali problem zatiskanja farmacevtskih aluminijastih tub. S trgalnim strojem in metodo digitalne korelacije slik smo izvedli natezne preizkuse materiala tube in pridobili podatke meritev odziva preizkušancev. Ti so bili osnova za izračun snovnih lastnosti, potrebnih za uspešen opis numeričnega modela. V nadaljevanju smo izvedli mehansko analizo zatiska aluminijaste tube, kjer smo preverili potek plastičnih deformacij zatisnjenega dela tube, določili zatisno silo in vpliv elastičnega izravnavanja.

Title:Computer simulation of aluminum tube sealing
Abstract:
Knowing material properties is essential in the field of engineering. In combination with functional equations that describe the behavior of the materials under certain effects we can correctly plan responses of the studied engineering problems. This final thesis examines the pharmaceutical aluminum tubes' sealing. With the tensile test machine and the method of digital image correlation we performed tensile tests for the material that forms the tubes. Additionally, we obtained information about the response measurements of the samples. Those were the basis for the calculation of material properties needed for efficient description of the numerical model. Also, we performed mechanical dynamical analysis of the aluminum tubes’ sealing process where we checked the plastic deformation course, determined the sealing force and the effect of elastic straightening.

Keywords:aluminum tube, digital image correlation, finite element analysis, tensile test, work hardening curve, non-linear dynamic analysis
