Abstract
Nosilca, ki je idealno vpet, idealno obremenjen in idealne geometrije v praktičnih aplikacijah ne moremo pričakovati. Imperfekcije, pa čeprav majhne, lahko povzročijo precejšnje odstopanje od teorije, ki opisuje idealen nosilec. V tej diplomski nalogi predstavimo napravo za preizkušanje vpliva različnih imperfekcij vpetja in obremenitve na odziv osno obremenjenega nosilca. Problem si najprej ogledamo z analitičnega vidika. Začnemo z eksaktno diferencialno enačbo upogibnice ukrivljenega nosilca, ki je izpeljana po teoriji 3. reda za velike premike ter iz nje izpeljemo enačbo upogibnice po teoriji 2. reda za majhne premike. Nato uporabimo eksperimentalno napravo, s katero preizkušamo vpliv začetne ukrivljenosti nosilca ter ekscentričnost vpetja pri uklonu. Rezultati meritev na preizkuševališču so primerjani z rezultati teoretičnih izračunov.

Title:Buckling of initially curved and imperfectly supported beam
Abstract:
Beam with ideal support, ideal geometry and ideally loaded cannot be expected in real engineering applications. Imperfections, though small, may cause substantial deviation from the theory, which describes ideal beams. In this diploma thesis, we present experimental apparatus for testing effects of different support and load imperfections on the response of axially loaded beam. The problem is first approached analytically with the derivation of the deflection equation of initially curved beam according to the exact and linearized theories. We use our experimental apparatus and test the effect of initial curvature and eccentric application of the load. The results of the measurements at the test site are compared with the results of theoretical calculations.

Keywords:buckling imperfections initial curvature eccentric load experimental apparatus
