Upogib kompozitnega nosilca na elastični podlagi

Rijavec, Jernej (author), Brojan, Miha (mentor)

Magistrsko delo obravnava deformacijsko in napetostno stanje kompozitne konstrukcije spremenljivega prereza, podprte z vzmetno podlago. Opravljena je analitična, numerična ter eksperimentalna analiza slalomske smuči in primerjalne kompozitne konstrukcije z nespremenljivim prečnim prerezom. Numerična analiza je izvedena po teoriji velikih premikov s pomočjo metode končnih elementov. Obremenitve in robni pogoji so definirani na podlagi standardnega upogibnega preizkusa, opravljenega v podjetju Elan. Opravljena je primerjava med rezultati numeričnega in analitičnega preračuna ter eksperimentalne analize.

• Title: Bending of a composite beam on an elastic foundation

Abstract

This dissertation analyzes strain and stress states of composite construction with variable cross section, supported by elastic foundation. Analytical, numerical and experimental analysis of slalom skis and a corresponding composite construction with a constant cross section was carried out. Numerical analysis was conducted according to the large deflection theory with finite element method. Boundary conditions and applied loads, corresponded to standard deflection test performed at company Elan. Comparison between analytical, numerical and experimental results was carried out.
