Abstract

Zadatak ovog završnog rada je provesti numeričku analizu čvrstoće ojačanih panela primjenom metode za izračun ekvivalentne krutosti panela. U prvom djelu rada je predstavljena i opisana metoda ekvivalentne krutosti panela, te analitički proračun koji se provodi pomoću programskog paketa Matlab. Glavni dio rada se bavi numeričkim modelom koji je dobiven korištenjem programa Abaqus/Standard, a nakon gotovih modela, opterećenih na izvijanje s različitim brojem i profilom uzdužnica, u trećem poglavlju prikazani su rezultati i njihova usporedba. Posljednje poglavlje rada je zaključak u kojem se nalazi detaljna analiza rezultata.

Abstract (english)

The aim of this thesis is to perform a numerical analysis of the stiffness of stiffened panels by applying a method for equivalent stiffness calculation of the panel. In the first chapter of the thesis, the method of equivalent stiffness of the panel, as well as the analytical calculation that is conducted by using the Matlab software package are presented and described. The main chapter of the paper deals with a numerical model created by using the Abaqus/Standard program. After the models have been completed, loaded to buckling with different number and profile of stringers, the results and their comparison are presented in the third chapter of the paper. The last chapter of the paper is the conclusion, which contains a detailed analysis of the results.
