Exceeding the Classical Time-bandwidth Product in Nonlinear Time-invariant Systems
Alireza Mojahed, Kosmas L. Tsakmakidis, Lawrence A. Bergman +1
The classical 'time-bandwidth' limit for linear time-invariant (LTI) devices asserts that it is impossible to store broadband waves (large Δω's) for long times (large Δt's). For st…
Toward understanding the self-adaptive dynamics of a harmonically forced beam with a sliding mass
Malte Krack, Noha Aboulfotoh, Jens Twiefel +3
A mechanical system consisting of an elastic beam under harmonic excitation and an attached sliding body is investigated. Recent experimental observations suggest that the system p…
Global complexity effects due to local damping in a nonlinear system in 1:3 internal resonance
Malte Krack, Lawrence A. Bergman, Alexander F. Vakakis
It is well-known that nonlinearity may lead to localization effects and coupling of internally resonant modes. However, research focused primarily on conservative systems commonly…
On the Efficacy of Friction Damping in the Presence of Nonlinear Modal Interactions
Malte Krack, Lawrence A. Bergman, Alexander F. Vakakis
This work addresses friction-induced modal interactions in jointed structures, and their effects on the passive mitigation of vibrations by means of friction damping. Under the con…
