    Investigation of mixed mode I and II fracture mechanical behaviour of SLS printed IASCB specimens by digital image correlation
    (2019) Campione, Ivo; Brugo, Tommaso Maria; Minak, Giangiacomo; Kos, Josip; Janković Tomić, Jelena; Ćirić Kostić, Snežana
    This work focuses on the fracture mechanics properties of polyamide (PA) for selective laser sintering (SLS) and investigates the capability of additive manufacturing process to build 3D artificial cracks, otherwise impossible to create by classic methods. IASCB semi-circular specimen with tilted crack subjected to asymmetric three-point bend loading were tested in order to cover a wide range of stress intensity factors (KI, KII and mixed modes) and T-stress. Moreover, Digital Image correlation (DIC) technique was used by full strain field analysis with the purpose of evaluating the fracture behaviour

    Primena optičke DIC merne metode na projektu A_MADAM
    (2018) Ćirić Kostić, Snežana; Janković Tomić, Jelena; Brugo, Tommaso Maria; Drvar, Nenad
    Aditivne tehnologije sve više se koriste u izradi funkcionalnih proizvoda koji su za vreme eksploatacije podložni dinamičkim opterećenjima. Cilj projekta AMADAM je utvrditi pravila dizajna, tako da s obzirom na način proizvodnje proizvodi aditivnih tehnologija imaju optimalna dinamička svojstva. Primenili smo optičku mernu metodu baziranu na digitalnoj korelacijli slike (DIC) za potrebe ispitivanja materijala, merenja pomaka i deformacija kod propagacije naprslina i verifikaciju i kalibraciju numeričkih simulacija. Eksperimente u prvoj fazi projekta provodimo na uzorcima od poliamida (PA) proizvedenim na SLS 3D printeru. Dosadašnja iskustva pokazala su da se odabrana DIC metoda pokazala jednostavnom za korišćenje a rezultati koje daje pružaju detaljni uvid u stvarno ponašanje konstrukcija.
