Abstract

To compare with the theoretical results of Part I,¹ detailed experimental results have been obtained on the nonlinear response of a clamped square plate under a uniformly distributed periodic load, which is subjected to various initial edge displacements. An aluminum test specimen with side length 200 mm and thickness 0·51 mm was used and tests were conducted by shaking the supporting frame with a constant peak acceleration and measuring the relative displacement of the plate to the frame. For the steady-state symmetric periodic responses, the theoretical results are found to be in good agreement with the experimental ones, with the exception of some quantitative differences in the large amplitude vibrations. Besides the responses theoretically predicted, a variety of non-symmetric and non-periodic responses were observed in connection with the internal resonance, combination resonance and dynamic snap-through phenomena, for which the present experimental results seem to provide effective data facilitating further theoretical analyses.

Effects of static loads on the nonlinear vibration of circular plates

The result is validated against an experiment in Yamaki et al. [2]. Later, the methodology was also adapted and applied to rectangular plates [3,4]. Hui [5,6] investigate the influence of imperfections on the dynamics of plates.
Maritime structures in water always experience a mean hydrostatic pressure. This paper investigates the nonlinear vibration of a clamped circular thin plate subjected to a non-zero mean load. A set of coupled Helmholtz–Duffing equations is obtained by decomposing the static and dynamic deflections and employing a Galerkin procedure. The static deflection is parameterized in the linear and quadratic coefficients of the dynamic equations. The effects of the static load on the dynamics, i.e. stiffening, asymmetry and softening, are investigated by means of the numerical solution of the coupled multi-mode system. An analytical solution of the single-mode vibration near primary resonance is derived. The analytical solution provides a theoretical explanation and quick quantification of the influence of the static load on the dynamics. The numerical and analytical results compare well, especially for lower values of the static deflection, confirming the effectiveness of the analytical approach. The proposed analysis method for plate vibration can be applied to other structures such as beams, membranes and combination forms.
A momentum subspace method for the model-order reduction in nonlinear structural dynamics: Theory and experiments
2020, International Journal of Non-Linear Mechanics

Yamaki & Chiba [10] proposed a method using Harmonic balance approach with a third order Galerkin approximation. The validation of this study was performed by Yamaki et al. [11] by conducting experiments on a square plate with clamped boundary conditions. A Galerkin discretization with symplectic integration was used to obtain backbone curves of simply supported rectangular plates with different aspect ratios by Leung & Mao [12].
The article proposes a method developed for model order reduction in a Finite Element (FE) framework that is capable of computing higher order stiffness tensors. In the method, a truncated third order asymptotic expansion is used for transformation of an FE model to a reduced system. The basis matrix in the formulation of the reduced-order model (ROM) is derived from linear mode shapes of the structure. The governing equations are derived using Hamilton’s principle and the method is applied to geometrically nonlinear vibration problems to test its effectiveness. An initial validation of the numerical formulation is obtained by comparison of results from time domain nonlinear vibration analyses of a rectangular plate using Abaqus. Subsequently, a stiffened plate is modeled to test a more complex structure and a continuation algorithm is used in combination with the ROM to compute nonlinear frequency response curves. The validation of the stiffened plate has been performed through comparisons with the results of nonlinear vibration experiments. The experiments are conducted with Polytec Laser Doppler Vibrometer and PAK MK-II measurement systems for large amplitude vibrations to validate the nonlinear vibration analyses.
Statics and Dynamics of Snap-through Effect
2017, Procedia Engineering
Snap-through effect i.e. sudden change of buckling surface is unpleasant phenomenon in behavior of structures especially in thin-walled structures. Geometric non-linear theory (The Total Lagrange Description) must be used. In geometric non-linear solution we have more results and snap-through effect can be explained as a jump between branches of solutions. It can be smooth but mostly this effect is sudden and accompanied with big noise. Examples of imperfect columns, von-Mises truss, shallow arch and steel thin-walled panels are presented.
Damping for large-amplitude vibrations of plates and curved panels, Part 1: Modeling and experiments

However, when it comes to experimental investigation, the literature is quite scarce. Non-linear vibrations of rectangular plates subjected to harmonic base excitation were investigated experimentally by Yamaki et al. [19]. Nguyen et al. [20] performed experimental tests to study the dynamic stability of rectangular plates having different boundary conditions and subjected to periodic in-plane loads.
Theoretical and experimental non-linear vibrations of thin rectangular plates and curved panels subjected to out-of-plane harmonic excitation are investigated. Experiments have been performed on isotropic and laminated sandwich plates and panels with supported and free boundary conditions. A sophisticated measuring technique has been developed to characterize the non-linear behavior experimentally by using a Laser Doppler Vibrometer and a stepped-sine testing procedure. The theoretical approach is based on Donnell's non-linear shell theory (since the tested plates are very thin) but retaining in-plane inertia, taking into account the effect of geometric imperfections. A unified energy approach has been utilized to obtain the discretized non-linear equations of motion by using the linear natural modes of vibration. Moreover, a pseudo arc-length continuation and collocation scheme has been used to obtain the periodic solutions and perform bifurcation analysis. Comparisons between numerical simulations and the experiments show good qualitative and quantitative agreement. It is found that, in order to simulate large-amplitude vibrations, a damping value much larger than the linear modal damping should be considered. This indicates a very large and non-linear increase of damping with the increase of the excitation and vibration amplitude for plates and curved panels with different shape, boundary conditions and materials.
Nonlinear vibrations of plates in axial pulsating flow
2015, Journal of Fluids and Structures
A theoretical approach is presented to study nonlinear vibrations of thin infinitely long and wide rectangular plates subjected to pulsatile axial inviscid flow. The flow is set in motion by a pulsating pressure gradient. The case of plates in axial uniform flow under the action of constant transmural pressure is also addressed for different flow velocities. The plate is assumed to be periodically simply supported in both in-plane directions with immovable edges and the flow channel is bounded by a rigid wall. In this way the system under study is a finite rectangular plate with conditions on the fluid and the plate boundaries coming from the periodicity of the infinite system. The equations of motion are obtained based on the von Kárman nonlinear plate theory retaining in-plane inertia via Lagrangian approach. The fluid model is based on the potential flow theory. The resulting Lagrange equations of motion of the coupled system contain quadratic and cubic nonlinear terms and are studied by using a code based on the pseudo-arc-length continuation and collocation scheme. The effect of different system parameters such as flow velocity, pulsation amplitude, pulsation frequency and channel pressurization on the stability of the plate and its geometrically nonlinear response to pulsating flow are fully discussed. It has been found that the presence of positive transmural uniform pressure and small pulsation frequency would destroy the pitchfork bifurcation (divergence) that flat plates exhibit when subjected to uniform flow. Moreover, in case of zero uniform transmural pressure numerical results show a hardening type behavior for the entire flow velocity range when the pulsation frequency is spanned in the neighborhood of the plate׳s fundamental frequency. On the contrary, a softening type behavior is presented when a uniform transmural pressure is introduced.

Although theoretical studies and literature reviews on nonlinear vibrations of plates are quite abundant, experimental studies are very scarce. Experiments on large amplitude vibrations of circular and rectangular plates subjected to harmonic base excitation were reported by Yamaki et al. [10,11]. Nguyen et al. [12] studied experimentally the dynamic stability of four rectangular plates subjected to periodic in-plane loads and subjected to four different sets of boundary conditions.
Large-amplitude (geometrically nonlinear) forced vibrations of completely free sandwich rectangular plates are investigated experimentally. Harmonic excitation is applied by using an electro-dynamic exciter and the plate vibration is measured by using laser Doppler vibrometers. A scanning laser Doppler vibrometer is used for experimental modal analysis since it provides non-contact vibration measurements with very high spatial resolution. The large-amplitude vibration experiments are carried out by using a single point laser Doppler vibrometer and a stepped-sine testing procedure. The nonlinear frequency response curves are obtained by increasing and decreasing the excitation frequency in very small steps at specific force amplitudes controlled in a closed-loop. The experimental results are compared to numerical simulations obtained by reduced-order models and show very good agreement. The nonlinear damping is experimentally obtained as a function of the vibration amplitude.
