Abstract

Predmet ovog rada je usporedba analitičkog i numeričkog proračuna čvrstoće zakovičnog spoja korištenog u zrakoplovnim konstrukcijama. U radu je prikazana analitička metoda korištena za proračun zakovične konstrukcije odabrane u ovom radu. Kroz rad je dan pregled korištenih načina modeliranja konstrukcije i provedba numeričke analize u programu Abaqus/Standard. Načini modeliranja zakovične konstrukcije u programu Abaqus/Standard su trodimenzionalna diskretizacija spoja i modeliranje spoja kinematskim vezama. Dana je analiza analitičkih i numeričkih rješenja odabranog zakovičnog spoja. Za spoj su korištene standardne aluminijske legure korištene u zrakoplovstvu. U zadnjem poglavlju je iznesen zaključak.

Abstract (english)

The subject of this Bachelor thesis is the comparison of analytical and numerical analyses of the strength of a riveted joint used in aircraft structures. The thesis presents the analytical method used to analyze the riveted structure selected for this work. Throughout the work, an overview of the modeling approaches used for the structure and the implementation of numerical analysis in the Abaqus/Standard software is provided. The described methods for modeling the riveted structure in Abaqus/Standard include three-dimensional discretization of the joint and modeling of the joint using kinematic constraints. An analysis of both the analytical and numerical solutions for the selected riveted joint is presented. Standard aluminum alloys commonly used in aeronautical engineering were used for the joint. The conclusion is presented in the final chapter.
