Abstract

V magistrski nalogi je obravnavan uklon dvakrat členkasto vpetega elastoplastičnega nosilca. Upoštevanih je več različnih neidealnosti, kot so začetna ukrivljenost, spremenljiva togost podpore in ekscentričnost delovanja obremenitve. Premična stanja ter zveze med obremenitvijo in premičnimi stanji so določene z uporabo teorije velikih premikov. Elastični materialni model je nadgrajen z modelom bilinearnega elastoplastičnega odziva. Rezultati so primerjani z eksperimenti in uveljavljenimi postopki dimenzioniranja tlačno obremenjenih nosilnih elementov.

Secondary title: Buckling of non-idealy simply supported elastoplastic beam with initial curvature
Secondary abstract: In this master thesis, the buckling of a simply supported elastoplastic beam is discussed. Several imperfections, such as the initial curvature, the variable support stiffness and the eccentricity of the load, are taken into account. The displacement states and load-displacement relations are determined using the theory of large displacements. The elastic material model is extended to a bi-linear elastoplastic model. The results are compared with experiments and established methods for the design of load-bearing structures subjected to compressive loads.
