Abstract (Croatian)

Predmet ovog rada je analiza globalnog i lokalnog gubitka stabilnosti uzdužnicama ojačanih zrakoplovnih panela. Provedena je analitička i numerička analiza radi usporedbe rezultata. U drugom i trećem poglavlju opisani su karakteristični konstrukcijski elementi zrakoplovnog panela te pojave koje vode lokalnom i globalnom gubitku stabilnosti. U četvrtom i petom poglavlju je napravljena analitička i numerička analiza gubitka stabilnosti. Analiza je provedena za tri različita profila uzdužnica, L, I i J profil. U šestom poglavlju je prikazana konvergencija rezultata, uspoređeni su rezultati numeričke i analitičke analize te je prikazan utjecaj promjene dimenzije struka uzdužnice na kritičnu silu izvijanja. U zadnjem, sedmom poglavlju, je zaključak.

Abstract

The content of this thesis is local and global buckling of stiffened panels. An analytical and numerical analysis was made to compare their results. The second and the thrid chapter describes characteristic structural elements of the airplane panel and the phenomena that lead to local and global buckling. An analytical and numerical analysis of local and global buckling of stiffeners was presented in the fourth and fifth chapter.The analysis was carried out for three different types of stiffeners, L, I and J profiles. The sixth chapter shows convergence of the numerical results, comparison of the numerical and analytical results. Additionally, a parametric study which shows the effect of various stringer web dimensions on the buckling load was performed in this chapter. The most important conclusions of this work are summarized in the seventh chapter.
