“…It is worth noticing that the VK model is naturally quadratic, whereas the Inxt model is cubic so that numerous additional variables (R p k , Q p k ) must be added, as in [42] for piezoelectric laminated beams. Other works [13,56] use elegant formulations of the equations of motion , first proposed in [31], using both the displacement and the velocity as variables. By expansion onto a suitable basis, a naturally quadratic formulation is obtained, which is exact without any restriction on the displacement/rotation magnitude.…”

“…The same subject is also addressed in [39] with a refined model based on a Cosserat theory of rods, that is used to compute nonlinear modes through the multiple scale perturbation method. Nonlinear resonance curves are also computed in [13], with a fully numerical approach based on a Galerkin discretization with Legendre polynomials and a continuation method (harmonic balance coupled to an asymptotic numerical technique).…”

“…The latter could be done by directly computing the truncated spectrum of Hill's matrix for a given periodic state. But a confusion subsists as for the sorting method one should use for the spurious computed spectrum, between eigenvalue [9,27,45] or eigenvector sorting [2,22,26,41]. Furthermore, only Floquet exponents are usually considered and modal informations from FFs are usually neglected.…”

“…The determination of their dynamic characteristics (natural frequencies and mode shapes) are of great importance in design and control. A significant number of studies have been published on the bending vibrations of rotating beams, with the main objective of predicting the natural frequencies and associated mode shapes, as well as investigating their variations with angular velocity and other effects such as hub radius, taper and shear deformation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. A review of several studies on rotating beams has been presented by Bazoun [19].…”

“…[27] used a dynamic model based on a geometrically exact approach and applied the MMS to construct the NNM. The nonlinearity depends on the angular velocity [17], and the rotating beam may exhibit hardening or softening behaviour depending on the geometric and kinematic conditions [13]. In [28], an algorithm is developed equivalent to the Lyapunov-Schmidt reduction for the computation of nonlinear free vibration curves from a Hopf bifurcation point.…”
