Dynamics of a Quasiperiodically-Forced Mathieu OscillatorMathieu’s equation ,.is the paradigm for problems in parametric excitation in which an autonomous linear structure is driven by a periodic forcer, usually in a direction perpendicular to the direction of motion (e.g., the vertically forced pendulum, dynamic buckling of an elastic column, water waves in a vertically driven channel).

Improved Galerkin Method in the Dimension Reduction of Nonlinear Dynamical SystemsWe apply the Karhunen-Loeve modes to improve the usual Galerkin reduction and compare this result with various other choices of ansatz functions. Moreover we also compare results obtained from a flat Galerkin reduction with those from a nonlinear Galerkin reduction making use of the Approximate Inertial Manifold method.

Bifurcation in Stochastically Perturbed Dynamical Systemsn (1) around each of these solutions. The standard procedure for this purpose is the evaluation of the maximal Lyapunov exponent which determines the exponential rate of growth or decay of some norm of the solution; the sign of the maximal Lyapunov exponent determines the stability of the trivial solution.

Jumps to Resonance Phenomena in Nonlinear Mechanics: Fractal Basins, Chaotic Transients and Unpredicisting attractor at the local bifurcation, jumps may be indeterminate in the sense that we cannot predict to which solution the system will settle upon. This is often a result fractal structure in the vicinity of the critical point resulting in chaotic transients until the settles onto one of the co-existing attractors

Nonstationary Responses in Two Degree-of-Freedom Nonlinear Systems with 1-to-2 Internal Resonanceequations are numerically studied for motions initiated in the vicinity of the stationary responses. An analytical technique, based on the . is then developed to explain the numerical observations for slow frequency sweep through the bifurcations, and the effects of system parameters on the dynamics near a Pitchfork Point are determined.
