Abstract
Kompozitni nosilci nam precej znižajo maso nosilne konstrukcije ob enaki ali celo izboljšani nosilnosti. Najpogosteje uporabljena oblika je enkrat simetrična kompozitna konstukcija. V diplomski nalogi smo obravnavali napetostno-deformacijska stanja v nosilcih z nesimetrično kompozitnim prečnim prerezom, kar pomeni, da je prečni prerez nesimetričen. V prvem delu diplomske naloge je predstavljen pristop k reševanju enkrat simetričnih kompozitnih nosilcev. V drugem delu smo izpeljali teorijo za obravnavo nesimetričnega kompozitnega prečnega prereza. Pravilnost izračunov smo preverili s primerjavo rezultatov izotropnega čistega upogiba ter enkrat simetričnega čistega upogiba. Z enako metodo smo rešili še primer kompozitnega nosilca iz več kot dveh materialov.

Title:Bending of composite beams with asymmetrical cross-section
Abstract:
Composite beams greatly reduce the mass of the supporting structure with the same or even improved load capacity. The most commonly used form is a symmetric composite structure. In this work we dealt with stress-strain states in beams with an asymmetrical composite cross-section. The first chapter presents the approach to solving single symmetric composite beams. In the second part, we deduced theory for solving beams of an asymmetric composite cross-section, and verified our method for solving and results by comparing them to the results of an isotropic pure bending and single symmetric pure bending. We applied the same method to solving composite beam, made of more than two materials.

Keywords:composite beam, asymmetric cross-section, stress state, systems of equations, bending
