Sentence examples for mode coupling phenomenon from inspiring English sources

The mechanism is considered a mode coupling phenomenon also referred to as coalescence.

Then, the paper addresses separately each mode coupling phenomenon, for columns, and only L-D interaction for beams.

In this study a method for the uncertainty quantification of friction induced vibrations based on the mode coupling phenomenon is shown.

Initially, column results are used to illustrate and help grasp some fundamental concepts, namely the characterisation of the (i) three above mode coupling phenomena, (ii) different sources of mode interaction that may cause ultimate strength erosion, (iii) global post-buckling behaviour and (iv) the most detrimental initial geometrical imperfections.

The aim of this work is to provide an overview of the current status of an extensive ongoing investigation on cold-formed steel columns and beams affected by mode coupling phenomena involving distortional buckling, namely local-distortional (L-D), local-distortional-global (L-D-G) and distortional-global (D-G) interaction.

The picture is different for columns experiencing D-G interaction and beams affected by L-D interaction, due to the lack of available experimental results − nevertheless, even if only numerical results are reported, they enable unveiling rather interesting (and unexpected) behavioural features concerning the real nature of these mode coupling phenomena.

Piezoelectrically actuated MEMS resonators can be very effective for building integrated frequency references in the radio frequency range even though experiments show that mode coupling and dissipative phenomena can affect their performance.

They also show that creak is caused by a stick slip phenomenon, squeal is mainly due to a mode-coupling phenomenon, while squeak can be caused either by mode-coupling or stick slip phenomena.

The free surface also brings intrinsic coupling phenomenon for the Mode I and Mode II SIFs.

The aim of this work is to investigate the instability scenarios occurring when friction forces excite the mechanical systems during the relative motion; simulation results show that the coupling between the frictional behaviour at the contact and the global dynamic of the system can bring to either stick slip phenomena, or mode coupling instability.

Complex eigenvalue analysis and transient non-linear simulations highlight how system parameters, like structural damping, affect the macroscopic frictional behaviour, switching from stick slip phenomena to harmonic vibrations (due to mode coupling instability), up to the stable sliding state.
