The annulus is simply supported and uniformly loaded on the outer edge, the inner edge is free and not loaded. The unstable state appears when the stress state is already in the elastic-plastic domain. The experimental results are compared to the results obtained from a mathematical model, which can take into account an idealized elastic, linear hardening, rheological model or a measured stress-strain curve. The paper describes the measuring procedure, the equipment and the choice of the material and the geometry of the specimens, which ensure that elastic-plastic buckling occurs during the experiment. The difference between the experimental and numerical results is 5.5%"},{"@xml:lang":"sl","#text":"Prispevek opisuje eksperimentalno določanje kritične obremenitve ter izbočitvenega koeficienta krožnega kolobarja konstantne debeline iz materiala z utrjevalno karakteristiko.
