Abstract
U ovome radu je nakon uvodnih razmatranja poroznih struktura, teorije vibracija, te osnovnih principa metode konačnih elemenata prikazan način izrade triju virtualnih modela kvadara s različitim periodički poroznim strukturama. Opisana je metodologija izvođenja modalne analize istih, te su prikazani rezultati u vidu prvih pet vlastitih frekvencija i formi vibriranja. Rezultati numeričke modalne analize su potom provjereni i potvrđeni eksperimentalnom modalnom analizom, te je ustanovljeno da su rezultati valjani.
Abstract (english)
In this thesis, after an introduction to porous structures, vibration theory and basic principles of the finite element method, the method of manufacturing of three virtual cuboids with unique periodically porous structures is presented. The methodology of conducting the modal analyis of said cuboids is described, and the results of considered analysis are presented in the form of the first five natural frequencies and mode shapes. The results of the numerical modal analysis were then verified and confirmed by an experimental modal analysis, and it was found that the results were valid.
