zaključna naloga Razvojno raziskovalnega programa I. stopnje Strojništvo
Abstract
V zaključni nalogi je predstavljen problem upogiba konzolno vpetega nosilca, obremenjenega z vertikalno in horizontalno silo ter momentom na prostem koncu. Nosilec se deformira elasto-plastično. Na začetku naloge so predstavljena dela ostalih avtorjev, ki so se ukvarjali z omenjenim problemom. Sledi izračun povesa elastičnega nosilca, v nadaljevanju pa je izračun nadgrajen z upoštevanjem elastično-linearno plastičnega in elastično-Ludwickovo plastičnega reološkega modela. Pri obeh modelih smo upoštevali še vpliv elastične podlage. Predstavljeni so tudi rezultati povesov razbremenjenega nosilca. V nalogi je tako predstavljena enostavna metoda za izračun povesov nosilcev, katera ima številne možnosti relativno enostavnega nadgrajevanja.

Secondary title: |
Bending of an elastoplastic cantilever beam on an elastic foundation |
Secondary abstract: |
n this thesis, bending of a cantilever beam, loaded with vertical and horizontal force and moment at free end, is presented. The beam deforms into elasto-plastically. In the beginning of the text, contributions of other authors, who worked on the mentioned problem, are presented. Next, calculating procedure for deflections of elastic beam is presented, followed by the upgrade of the model into elastic-linear plastic and elastic-Ludwick plastic rheology model. In both models, the influence of elastic foundation is considered. The springback deflections are also studied. Our simple method for computing cantilever beam deflections can relatively easily be upgraded. |
