Abstract
The stability of perfect bifurcational discrete dissipative systems under follower loading in regions of existence/non-existence of adjacent equilibria is reexamined in the light of recent progress in nonlinear dynamics. A general qualitative theory for such non-potential autonomous systems which may exhibit a periodic attractor in addition to a point one is developed. Conditions for the existence of adjacent equilibria and for different types of local dynamic bifurcations are established. Focusing attention on the coupling effect of geometric (and/or material) nonlinearities and vanishing damping new findings contradicting widely accepted results of the classical (linear) analysis are explored. Thus, in a small region of adjacent equilibria it is found that the static stability criterion may fail to predict the actual critical load.
