New Instability Aspects for Nonlinear Nonconservative Systems with Precritical Deformation,therwise the latter loads are always less than the former.It was also found that systems statically stable may be proven unstable when a nonlinear dynamic analysis is employed. Clobal bifurcations have revealed that this autonomous system even when damping is excluded may exhibit phenomena looking like chaos.

Analysis of Dynamical Systems by Truncated Point Mappings and Cell Mapping,urbation method employed here, we obtain a powerful tool for finding periodic solutions and for analyzing their stability. A new approach for analyzing nonlinear systems which combines the techniques of truncated point mapping and cell mapping methods is also described here.

Effect of Constant Transverse Force on Chaotic Oscillations of Sinusoidally Excited Buckled Beam,dict the onset of chaos. For a large transverse constant force, there exists only one static equilibrium point, but there may exist three different dynamic response amplitudes due to nonlinear resonance phenomena. The near contact between two vibration regions of a stable and an unstable limit cycle can predict the onset of chaos.

Conference proceedings 1990eering Systems held in 1989 in Stuttgart, FRG. The Symposium was intended to bring together scientists working in different fields of dynamics to exchange ideas and to discuss new trends with special emphasis on nonlinear dynamics in engineering systems. A Scientific Committee was appointed by the B

Liapunov Stability Analysis for Control of Flexible Manipulators, method for this model yields a nonlinear lumped-parameter differential equation with finitely large or infinite dimension including centrifugal and Coriolis forces. Stability of PD and PDS (PD + Strain) feedback control schemes is discussed on the basis of Liapunov’s method applied for the lumped — parameter model.
