Abstract

Tema ovog diplomskog rada je primjena pojednostavljenih pristupa modeliranju oštećenja na procjenu preostale čvrstoće višeslojnih kompozitnih ploča. Analiza je provedena programom za numeričku analizu metode konačnih elemenata Abaqus/Standard. Validacija modela izvršena je uspoređivanjem dobivenih numeričkih rezultata s postojećim eksperimentalnim rezultatima iz dostupne literature. U prvom poglavlju napravljen je kratak uvod o višeslojnim kompozitnim konstrukcijama i njihovim načinima popuštanja. Drugo poglavlje govori o pojednostavljenim pristupima modeliranja oštećenja, dok su numeričke analiza opisane u trećem poglavlju. Četvrto poglavlje sadrži rezultate analiza, uz validaciju s eksperimentalnim rezultatima, te zaključak gdje je cijeli rad ukratko izložen.

Abstract (english)

The topic of this Master thesis is the application of a simplified damage modeling approaches for residual strength prediction of laminated composite plates. The analysis was performed by the program for numerical analysis using the finite element method Abaqus/Standard. Validation of the numerical model was performed by comparison of obtained numerical results with the experimental results from available literature. In the first chapter, a brief introduction was made about laminated composite structures and their failure modes. The second chapter talks about simplified damage modeling approaches, while the numerical analysis is described in the third chapter. The fourth chapter contains the results of the analysis, along with validation with experimental results, and the conclusion in which the complete work is briefly presented.
