heal.abstract	The nonlinear dynamic buckling based on the global response of a nonlinear autonomous dissipative or non-dissipative system with two degrees of freedom is studied in detail. Attention is focused on the unstable branch of the complementary path whose significant role on the mechanism of dynamic buckling is revealed for the first time in the literature. Theoretical results associated with distinct properties of the Jacobian matrix, verified and supplemented numerically, brought into light various new phenomena for certain values of the control parameter such as dynamic buckling of statically stable systems, metastability phenomena for loads much higher than the dynamic buckling loads, and sensitivity to initial conditions and to damping.	en
