Abstract

3D ispisom moguće je napraviti umjetnu repliku neopterećene arterije koja se u fiziološkom rasponu tlakova ponaša slično stvarnoj žili. Korišteni polimerni materijali opisani su Neo-Hooke materijalnim modelom. Cilj ovog rada je određivanje geometrije 3D ispisane konusne replike krvne žile te priprema modela aneurizme aorte za proizvodnju 3D ispisom. Modeli su dobiveni numeričkom metodom temeljenom na mehanici kontinuuma. Iz poznatih podataka dimenzija pravih ljudskih krvnih žila pri dijastoličkom i sistoličkom tlaku iterativnim postupkom izračunava se neopterećena geometrija replike krvne žile prigodna za 3D ispis. U radu je izveden numerički postupak, primijenjen je na konusnu žilu i aneurizmu te su modeli verificirani metodom konačnih elemenata.

Abstract (english)

Artificial unloaded artery replicas, 3D-printed using Neo-Hookean material models, simulate the mechanical behavior of real vessels under physiological pressure ranges. This research focuses on defining the geometry of 3D-printed conic blood vessel replicas and preparing aortic aneurysm models for 3D manufacturing. Employing continuum mechanics, an iterative numerical approach determines the unloaded vessel geometry based on diastolic and systolic human vessel dimensions. Finite element analysis was employed to validate the resulting conic blood vessel and aneurysm models.
