Abstract
U ovome diplomskom radu obrađeni su i numerički analizirani kompozitni nosači (sendvič paneli) pomoću metode konačnih elemenata. Na početku rada prikazano je općenito o kompozitnim materijalima i njihova primjena u sendvič panelima, te najčešći načini otkaza sendvič panela. Druga cjelina pobliže objašnjava metodu konačnih elemenata s posebnim naglaskom na kontaktne elemente. Sljedeća cjelina se bazira na numeričkoj analizi kompozitnih grednih nosača opterećenih na savijanje u tri točke, uz promjenu gustoće i različite visine jezgre ali jednaku debljinu obloge. Četvrta cjelina prikazuje usporedbu dobivenih numeričkih rezultata s poznatim analitičkim rješenjima i rezultatima pokusa iz dostupne literature. Posljednja cjelina ima zadatak optimiranja geometrije i sastava kompozitnog grednog nosača, kako bi se pronašao najučinkovitiji presjek i najbolja realistična svojstva.
Abstract (english)
In this thesis, composite supports and beams (sandwich panels) are processed and numerically analyzed using the finite element method (FEM). At the beginning of the work, composite materials and their application in sandwich panels are generally presented, as well as the most common ways in which sandwich panels fail. The second section provides a detailed explanation of the FEM with a special emphasis on contact elements. The following section is based on the numerical anaysis of composite beam supports on three-point bending, with varying density and different core heights but equal face-sheet thickness. The fourth section shows a comparison of the obtained numerical results with known analytical solutions and results from experiments in the literature. The last section aims to optimise the geometry and composition of the composite beam support in order to find the most efficient cross-section and best realistic properties.
