20.500.12556/RUL-127280 Napetostno stanje kompozitnega nosilca poljubnega prereza obremenjenega s kombinacijo torzije in upogiba Stress state of a composite beam of arbitrary cross-section under a combined torsional and bending load Torzija homogenih prizmatičnih nosilcev je relativno dobro raziskana, malo več pozornosti pa je treba nameniti teoriji, ki analizira torzijo kompozitnih nosilcev s spreminjajočimi se materialnimi lastnostmi. V tem magistrskem delu smo se osredotočili na kompozitni nosilec, ki je obremenjen s torzijsko in upogibno obremenitvijo. Rezultat tega je netrivialno napetostno polje po prerezu. V delu prav tako primerjamo rezultate teorije z rezultati, ki smo jih določili eksperimentalno. Zaradi enostavnejšega računanja smo razvili tudi uporabniški vmesnik, ki služi za hitrejše določevanje in izračunavanje prerezov nosilcev. The torsion of homogeneous prismatic beams is relatively well researched. A theory that needs more attention, however, is the one that analyses torsion of composite beams with changing material properties. In this master's thesis, we focused on a composite beam loaded with torsional and bending loads. The result is a non-trivial stress field across the cross-section. We also compared the results of the theory with the results obtained with experimental testing. To achieve simpler calculation, we also developed a user interface that serves as a tool for a faster determination and calculation of stresses on the beam cross-section. torzija kompozitnih nosilcev napetostno polje na prerezu upogib kompozitnega nosilca Saint Venant Mathematica torsion of composite beams stress distribution function in cross-section bending of composite beam Saint Venant Mathematica true false false [F.
