Qualitative Analysis of Forced Response of Blisks With Friction Ring Dampers

[7] developed a finite element model for vibration analysis of active–passive damped multilayer sand- wich plates, with a viscoelastic core sandwiched between elas- tic

A new differential equation is introduced having periodic stiffness variation and clearance type non-linearity which has been shown experimentally to describe accurately

Zoom on the closed curve solution and the forced localization that arise in the case of a localized excitation (—: stable, : unstable, : linear response, – –: backbone

On the other hand, the nonlinear contribution to the fluctuations of the injected power depends on the nature of the forcing; it is significantly larger for the periodic forcing 共 60%

Stability and response analysis of a pipe with internal flow analyzed with an uncertain computational model.. COMPDYN 2013, 4th ECCOMAS Thematic Conference on Computational Methods

The formulation, termed Modified Wave Finite Ele- ment (MWFE), allows the global wave modes of a given multi-layered system to be constructed from the local wave mode bases attached

The waveguide is discretized by means of 200 identical substructures, each of these being discretized by means of 4 × 6 linear finite elements (see Figure 1(a)). In this case,
