Bifurcation‒Harmonic Coupling Mechanism and Subharmonic Threshold in One-dimensional Nonlinear Elastic Waves

工程科学与技术
ObjectiveNonlinear harmonics are sensitive indicators of early-stage material degradation and microdamage. However, their generation strongly depends on the excitation frequency, amplitude, and nonlinear dynamic state of the material, leading to ...

Bifurcations and Subharmonics in the Nonlinear Motions in a Narrow Band Irregular Sea

, 1992
The possibility of bifurcations in first order nonlinear motions in stochastic sea is analysed by means of a multiscale perturbation method. The results indicate that this feature can be present in many systems of interest to Naval Architecture and Ocean

ON THE BIFURCATIONS OF SUBHARMONICS IN REVERSIBLE-SYSTEMS

Following Vanderbauwhede's approach [23], the study of the local bifurcation of subharmonics in reversible systems leads to reduced equations equivariant under the dihedral groups. Depending on the dimension of the space, or on the type of the involution,
