Abstract
A general qualitative approach for the dynamic Buckling and
Stability of autonomous dissipative structural systems is
comprehensively presented. Using the theory of local and
global bifurcations, of the Jacobian eigenvalues, of point and
periodic attractors, of the basin of attraction and of the inset
and outset manifolds, the mechanism of dynamic buckling is
thoroughly discussed. This allows us to establish useful
criteria leading to exact and upper/lower bound buckling
estimates without integrating the highly nonlinear initial-value
problem. A comparison of the results of the above qualitative
analysis with those obtained via numerical simulation and an
approximate analytic technique, is performed on two simple of
engineering importance models.
