Abstract (Croatian)

Izraženo smično opterećenje značajnog intenziteta može izazvati pojavu smičnog izvijanja, a u konačnici izazvati i smični kolaps smično opterećenih elemenata konstrukcije trupa broda, ukoliko narinuto opterećenje nadmaši njihovu smičnu graničnu nosivost. Stoga, razmatranje smične nosivosti ukrepljenih ploča može predstavljati relevantan aspekt i važan kriterij strukturne podobnosti u okviru analize i sinteze kostrukcije broda. S obzirom da se postojeće formulacije smične granične nosivosti zasnivaju na korekciji kritičnog smičnog naprezanja pri elastičnom smičnom izvijanju, u okviru ovoga rada se razmatraju različiti mogući načini odgađanja pojave elastičnog smičnog izvijanja te se identificira najefektivniji prisup s tim u vezi. Na temelju relevantnih teorijskih aspekata i rezultata provedenih analiza razmatranog problema metodom konačnih elemenata, predložena je formulacija za određivanje kritičnog smičnog naprezanja prikladno ukrepljenih ploča.

Abstract

Pronounced shear loading of the significant intensity can induce occurrence of the shear buckling and eventually lead to the shear collapse of the hull girder structural elements loaded in shear, if acting shear load surpasses their ultimate shear load capacity. Therefore, consideration of the stiffened plate shear load capacity can represent a relevant aspect and important structural adequacy criterion in analysis and synthesis of the ship structures. Since the contemporary ultimate shear load capacity formulations are based on correction of the calculated elastic shear buckling critical stress, this paper investigates various possible approaches to inhibition of the elastic shear buckling and identifies the most effective one. Based on relevant theoretical aspects and results of the performed finite element method analyses of the considered problem, a formulation for determination of the critical shear stress for the appropriately stiffened plates is proposed.
