Abstract
U radu se bavimo analizom naprezanja i deformacija zakrivljenih štapova te usporedbi istih s ravnim štapnim elementima. Promatramo što se dešava s elementom kada je opterećen uzdužnom silom, poprečnom silom i djelovanjem momenta, te kako računski dobivamo iznose deformacija i naprezanja. Bitno je poznavati geometrijske karakteristike poprečnih presjeka kako bi što jednostavnije odredili polumjer zakrivljenosti neutralnog sloja te saznali u kojoj točki presjeka nam se nalazi neutralna os. Analizom raspodjele normalnih naprezanja kod pravokutnog poprečnog presjeka, uspoređujemo odstupanja rezultata u odnosu na ravne nosače. Numeričkim primjerima dobivamo iznose odstupanja te na temelju toga dolazimo do podjele štapova na štapove velike i male zakrivljenosti. Kako bi iskoristivost elemenata bila maksimalna, prikazani su racionalni oblici poprečnih presjeka s obzirom na to ima li promatrani materijal ista ili različita svojstva kada govorimo o vlačnim i tlačnim naprezanjima.
Abstract (english)
This final work deals with the analysis of stresses and strains of curved rods and their comparison with flat rod elements. We observe what happens to an element when it is loaded with longitudinal force, transverse force and the action of bending moments, how we calculate the amounts of strain and stress. It is important to know the geometrical characteristics of the cross-sections in order to determine the radius of curvature of the neutral layer as easily as possible, and to find out at which point of the cross-section our neutral axis is located. By analysing the distribution of normal stresses in a rectangular cross section, we can compare the deviations of the results with respect to the flat rods. Numerical examples show us the amounts of deviations, and based on that we divide rods into rods of large and small curvature. In order to maximize the efficiency of the elements, rational cross-sectional shapes are presented with regard to whether the observed material has the same or different properties when we talk about tensile and compressive stresses.
