Abstract

Buckling localization of a rotating disk made of elastic-perfectly plastic material is investigated using stress-rate formulation of the stability boundary-value problem. The phenomenon of plastic buckling localization and its analogy with elastic buckling localization is discussed. For a thin rotating disk, it is shown that buckling develops at a speed lower than one at which the disk passes to fully plastic state, or in other words, before the limit load has been attained.
