Modal analysis shows the existence of three types of modes for the combined structure, depending on the involvement of each substructure.
Simulations indicate that two types of mode families are possible; "bandgap guided" and; "index guided".
From the modal analysis of the ambient vibration data, two types of mode shapes are identified by operational modal analysis.
The planar deformation has two types of mode shapes; i.e., in-plane and out-of-plane.
Five types of mode are identified according to their mode shape characteristics; these are radial, edge, thickness shear, thickness extensional and high frequency radial modes.
It has also been used to test the predictions of the theories of Kirkhope for the four types of mode, and the theory of Bickford and Maganty for axial and torsional modes.
Two types of modes are found: rotational and translational modes.
We see that the measurement operator now consists of two types of modes, βk and, which are superpositions of two momentum states, k and k − π/a.
Experiments, and recent large eddy simulations, indicate that switching takes place between these two types of modes while in other cases a single mode type prevails.
It is shown in particular that in the medium-frequency range, there are two types of modes: global modes and spatially localized modes.
It is found that there are two types of modes of oscillation possible which are consistent with the kinematic assumptions made to find the semi-inverse solution.
