Abstract
Tijekom istraživačkog projekta u kojem su se provela ispitivanja na lijepljenim aluminijskim spojevima, dogodilo se neočekivano plastificiranje aluminija. U ovom završnom radu detaljnije će se istražiti elastoplastično ponašanje aluminija te odrediti ključne parametre koje ga opisuju. Provest će se niz eksperimenata u 3 faze. U prvoj fazi će se uzorci aluminija jednoosno vlačno opteretiti do sloma dok će se u sljedeće dvije faze isti uzorci ciklički opterećivati i rasterećivati. U drugoj fazi aluminij će se najprije opteretiti vlačno, a u trećoj tlačno. Cilj je na temelju rezultata eksperimenata tj. radnih dijagrama svakog uzorka, odrediti parametre aluminija koji će se potom koristiti za bilinearni materijalni model. Algoritam koji opisuje bilinearni model sastoji se od više funkcija naprezanja u ovisnosti deformacije te za zadanu trenutnu deformaciju računa naprezanje u odnosu na naprezanje i deformaciju u prethodnom koraku. Ovakvim bilinearnim modelom će se aproksimirati materijalno ponašanje aluminija u numeričkim simulacijama za raslojavanje lijepljenih aluminijskih spojeva.
Abstract (english)
During a research project in which tests on adhesively bonded aluminium joints were performed, unexpected yielding of aluminium occurred. In this undergraduate thesis, elasto-plastic behaviour of aluminium will be investigated in detail and the key parameters that define it will be determined. A series of experiment will be performed in three phases. In the first phase, aluminium specimens will be uniaxially loaded in tension, while in the remaining two phases the same specimens will be cyclically loaded and unloaded. In the second phase, aluminium will be first loaded in tension, whereas in the third phase it will be first loaded in compression. Based on the experimental results, i.e. the strain-stress curves for each specimen, the goal is determining the parameters of aluminium, which later will be used for a bi-linear material model. The algorithm that describes the bi-linear model is composed on several stress functions that are dependent on the stress and strain in the previous step. This bi-linear model will be used to approximate the material behaviour of aluminium in numerical simulations of delamination of adhesively bonded aluminium joints.
