Abstract (sommario):

The presence of a crack in a structure modifies the energy dissipation pattern. As a consequence, damaged structures can present high localized damping. Experimental tests have revealed that crack nucleation and growth increase structural damping which makes this phenomenon useful as a damage locator. This paper examines the energy flow patterns caused by localized damping in rods, beams and plates using the Energy Finite Element Method (EFEM), the Spectral Element Method (SEM) and the Energy Spectral Element Method (ESEM) in order to detect and locate damage. The analyses are performed at high frequencies, where any localized structural change has a strong influence in the structural response. Simulated results for damage detection in rods, beams, and their couplings calculated by each method and using the element loss factor variation to model the damage, are presented and compared. Results for a simple thin plate calculated with EFEM are also discussed.

Abstract (sommario):

Context. Solar magnetic pores are, due to their concentrated magnetic fields, suitable guides for magnetoacoustic waves. Recent observations have shown that propagating energy flux in pores is subject to strong damping with height; however, the reason is still unclear. Aims. We investigate possible damping mechanisms numerically to explain the observations. Methods. We performed 2D numerical magnetohydrodynamic (MHD) simulations, starting from an equilibrium model of a single pore inspired by the observed properties. Energy was inserted into the bottom of the domain via different vertical drivers with a period of 30 s. Simulations were performed with both ideal MHD and non-ideal effects. Results. While the analysis of the energy flux for ideal and non-ideal MHD simulations with a plane driver cannot reproduce the observed damping, the numerically predicted damping for a localized driver closely corresponds with the observations. The strong damping in simulations with localized driver was caused by two geometric effects, geometric spreading due to diverging field lines and lateral wave leakage.

Abstract (sommario):

Dans le dimensionnement des lanceurs spatiaux, la maîtrise de l'amortissement est une problématique majeure. Faute d'essais sur structure réelle très couteux avant la phase finale de qualification, la modélisation de l'amortissement peut conduire à un sur-dimensionnement de la structure alors que le but recherché est de diminuer le coût du lancement d'une fusée tout en garantissant le confort vibratoire de la charge utile.Nos contributions sont les suivantes. Premièrement, une méthode de prédiction par le calcul des niveaux vibratoires dans les structures de lanceurs en utilisant une stratégie d'essais virtuels qui permet de prédire les amortissements en basses fréquences, est proposée. Cette méthode est basée sur l'utilisation de méta-modèles construits à partir de plans d'expériences numériques à l'aide de modèles détaillés des liaisons. Ces méta-modèles peuvent être obtenus grâce à des calculs spécifiques utilisant une résolution 3D par éléments finis avec prise en compte du contact. En utilisant ces méta-modèles, l'amortissement modal dans un cycle de vibration peut être calculé comme étant le ratio entre l'énergie dissipée et l'énergie de déformation. L'approche utilisée donne une approximation précise et peu coûteuse de la solution. Le calcul non-linéaire global qui est inaccessible pour les structures complexes est rendu accessible en utilisant l'approche virtuelle basées sur les abaques.Deuxièmement, une validation des essais virtuels sur la structure du lanceur Ariane 5 a été élaborée en tenant compte des liaisons boulonnées entre les étages afin d'illustrer l'approche proposée. Lorsque la matrice d'amortissement généralisé n'est pas diagonale (car des dissipations localisées), ces méthodes modales ne permettent pas de calculer ou d'estimer les termes d'amortissement généralisé extra-diagonaux. La problématique posée est alors la quantification de l'erreur commise lorsque l'on néglige les termes extra-diagonaux dans le calcul des niveaux vibratoires ; avec un bon ratio précision / coût de calcul.Troisièmement, la validité de l'hypothèse de diagonalité de la matrice d'amortissement généralisée a été examinée et une méthode très peu coûteuse de quantification a posteriori de l'erreur d'estimation de l'amortissement modal par la méthodes des perturbations a été proposée.Finalement, la dernière contribution de cette thèse est la proposition d'un outil d'aide à la décision qui permet de quantifier l'impact des méconnaissances sur l'amortissement dans les liaisons sur le comportement global des lanceurs via l'utilisation de la méthode info-gap
In the dimensioning of space launchers, controlling depreciation is a major problem. In the absence of very expensive real structural tests before the final qualification phase, damping modeling can lead to over-sizing of the structure while the aim is to reduce the cost of launching a rocket while guaranteeing the vibratory comfort of the payload.[...]

Abstract (sommario):

Cette thèse traite trois problèmes liés à la stabilisation des équations des ondes. Nous considérons différents cadres fonctionnels et nous utilisons des techniques de démonstration basées sur la méthode des multiplicateurs. Tout d'abord, nous étudions la stabilité de l'équation des ondes avec un amortissement non-linéaire et localisé dans un cadre hilbertien standard en dimension deux. La preuve est basée sur des travaux existants dans le cas d'un amortissement non-localisé. Rajoutons une localisation ainsi que des perturbations. Nous démontrons la stabilité exponentielle le long des solutions fortes en l'absence de perturbation ainsi qu'une sorte stabilité au sens Input-To-State par rapport aux perturbations considérées. Dans un deuxième travail, nous considérons un cadre fonctionnel plus général non forcément hilbertien, c-a-d un cadre L^p avec p appartient (1,infini). Nous étudions la stabilité L^p de l'équation des ondes avec un amortissement linéaire et localisé. Cette étude n'est effectuée qu'en dimension un car il n'est pas toujours possible de définir l'opérateur des ondes en dimensions supérieures lorsque p différent 2. Nous démontrons la stabilité exponentielle du problème en généralisant les multiplicateurs du cadre hilbertien dans notre cadre plus général, avec des preuves différentes suivant que 1 2. Nous démontrons également dans le même problème mais avec des cas particuliers d'un amortissement global et constant, une stabilité exponentielle dans le cas p=1 et p=infini. Dans un troisième travail, nous considérons la version non-linéaire du problème précédent: en nous basant sur une technique de linéarisation, nous nous ramenons à la preuve du problème linéaire pour démontrer la stabilité exponentielle du non-linéaire
This thesis focuses on three problems in the context of the stabilization of wave equations. We consider different frameworks and we use techniques based on the multipliers method. First, we study the stability of the wave equation with non-linear localized damping in a standard Hilbertian framework in two dimensions. The proof is based on the work already existing in the case of a non-localized damping. We add a localization as well as disturbances. We prove the exponential stability of strong solutions in the absence of disturbances and also a weak Input-To-State stability property with respect to the considered disturbances. We next consider a more general functional framework, namely an L^p framework with p in (1,infty). We study the L^p stability of the wave equation with a linear and localized damping in one dimension since it is not always possible to define the wave operator in higher dimensions when p = 2. We prove the exponential stability of the problem by generalizing the multipliers of the Hilbertian framework in this new general framework, with a different proof for 1 2. We also prove in the same problem but with particular cases of a global constant damping, an exponential stability in the case p=1 and p=infty. We consider next the nonlinear case of the previous problem: relying on a linearizing technique, we reduce that study to that of the linear problem case in order to prove the exponential stability of the non-linear problem

Abstract (sommario):

El presente trabajo, consiste en la implementación de estos disipadores fluido-viscosos en una edificación con predominación de muros estructurales de 5 niveles que presenta un comportamiento torsional. El diseño de estos disipadores, parten con el objetivo de diseño de daño moderado y bajo un sismo de 475 años de periodo de retorno, es decir que la deriva objetivo necesario para el diseño es 0.58%. Se analiza bajo la colocación en diagonal para amortiguadores lineales y no lineales. La colocación se hace de manera uniforme, y de manera que compense el movimiento torsional. Se colocaron un total de 40 disipadores en todo el edificio. Entre los principales resultados, la fuerza fuerzas en los disipadores fueron en un orden de 213 ton-f y comportamiento torsional debido a zonas frágiles de la estructura fueran reducidas en 80%. La implementación de los disipadores fluido-viscosos permiten reducir la deriva en 60% y todas las derivas se mantienen por debajo de 0.58%, en teoría. En un futuro, en el Perú, será necesario implementar una normativa para el diseño y el aporte de amortiguamiento en el edificio.
The present work consists of the implementation of these fluid-viscous dissipators in a building with a predominance of structural walls, of 5 levels that presents a torsional behavior, as well as fails to comply with the permissible drift limit established by Norma Técnica E.030. The design of these dissipators starts with the design objective of moderate damage and under an earthquake of 475 years of return period, whose corresponding objective drift assumes a value of 0.58%. It is discussed under diagonal placement for linear and nonlinear dampers. The placement is done uniformly, and in a way that compensates for torsional movement. A total of 40 heatsinks were placed throughout the building, 8 per floor. Among the main results, the forces in the dissipators were in the order of 200 ton-f and torsional behavior due to flexible areas of the structure were reduced by 80%. The implementation of fluid-viscous heatsinks allows the drift to be reduced by 60%, and all drifts are kept below 0.58%, that is, both linear and non-linear devices meet the target drift, even though the latter have a higher drift, given their lower C, therefore, lower force, less drift control, even so, they are efficient, both structurally and economically, given their lower strength. In the future, in Peru, it will be necessary to implement a regulation for the design and the cushioning contribution in the building.

Abstract (sommario):

This thesis is subdivided into two parts: in the first we analyze the transition from static to dynamic friction with some emphasis on the implication of using more refined friction laws (with respect to the simple Coulomb model) while in the second part we study the cyclic response of dynamical systems that experience friction. Particularly, in the first part we will take inspiration from some recent experiments from the group of Prof. Fineberg to tackle some partial slip contact problems, with the idea in mind of providing analytical models that can, in some extent, interpreter some of the numerous experimental evidences that came from the direct observation of the sliding phenomena. In the chapters 1-2 a brief introduction of the equations that govern the contact of elastic bodies and the experimental test rig used in the experiments is presented. In chapter 3 the partial slip problem of a flat square-ended punch pressed against an half-plane and tangentially loaded above the contact interface is studied, then a FEM of the Prof. Fineberg experimental test rig will be proposed to avoid the hypothesis of half-plane elasticity, with good agreement between numerical and experimental results. In chapter 4 the implications of using a slip weakening friction law instead of the classical Coulomb law are discussed and an energetic criterion for slip inception is derived, which we will call "Griffith friction model". In chapter 5, using this "Griffith friction", the partial slip problem for different plane geometries (power law punches and sinusoidal profile) is solved. In the second part of the thesis we will focus our attention on the dynamic response of mechanical systems subjected to friction. In chapter 7 a very simple model of structure subjected to dry friction is studied, constituted by a single degree of freedom system subjected to a periodical tangential excitation and a (possibly) varying normal load. First we compare the quasi-static solution with the dynamic solution in the limit of very low excitation frequency, then we study (in the bounded regime) how the peak displacement and dissipation is related to the phase shift between the normal and the tangential load. In chapter 8 the dynamical behavior of a mass-spring-viscous damper structure linked to a massless Coulomb damper is studied with attention to the regime that minimize the vibration amplitude of the mass. Finally in chapter 9, we study a friction-excited nonlinear oscillator chain, where a polynomial nonlinearity is introduced in the system. We focus our attention on the multiplicity of solutions that are proven to exist in certain parameter rangeS which leads to a bifurcation pattern similar to the snaking bifurcations. In the end conclusions and possible developments of the present work are proposed.

Abstract (sommario):

Concurrent placement of compact active and passive damping patches for vibration reduction is a developing area of research. Analytical and computational models to evaluate alternate patch configurations and structural geometries are not widely available. To overcome this void, this paper presents a simplified discrete-system model for vibrations of a beam-like structure. A disturbance input is included in the model, along with a control input from an active patch. Localized structural damping resulting from a passive patch is modeled with an equivalent loss factor. Results from the simplified model are verified using a more detailed analytical formulation, which is based on the Ritz approximation. Verification studies include the effect of a passive damping patch on modal loss factors and broadband attenuation. Finally, a few case studies are proposed which show the efficacy of the reduced-order model for parametric design studies. These studies include determining the effect of localized damping on the control system parameters that are required for attenuation of localized and global motions. The effect of patch locations on system response is also studied. This work has potential applications in industry since compact damping patches are attractive NVH treatments that add minimal weight and complexity.

Abstract (sommario):

Abstract A parametrically excited mode-localized acceleration threshold sensor was designed by using the Supercritical Hopf (SCH) bifurcation with high robustness to the fluctuation of driving voltage and damping while maintaining high sensitivity. The multi-physical dynamic model is established considering both the mechanical and electrical nonlinearities. At the SCH bifurcation point, small acceleration will change the topological structure from SCH bifurcation to Saddle-Node (SN) bifurcation, and the corresponding sensitivity (amplitude ratio) can reach 10000%/g in a dynamic range of ±0.001g. Additionally, the transmission process of the amplitude ratio is similar to the Sign function, which can be used as a threshold switch.

Abstract (sommario):

In this work, the arising of stick-slip dissipation as well as the global mechanical response of carbon nanotube (CNT) nanocomposite films are tailored by exploiting a three-phase nanocomposite. The three phases are represented by the CNTs, a polymer coating localized on the CNTs surface and a hosting matrix. In particular, a polystyrene (PS) layer coats multi-walled carbon nanotubes (MWNTs) that are randomly dispersed in a polyimide (PI) matrix. The coating phase is strongly bonded to the CNTs outer sidewalls ensuring the effectiveness of the load transfer mechanism and reducing the material damping capacity. The coating phase can be thermally-activated to modify, and in particular, decrease the CNT-matrix interfacial shear strength (ISS) thus facilitating the stick-slip onset in the nanocomposite. The ISS decrease finds its roots in a partial degradation of the coating phase and, in particular, in the formation of voids. By weakening the CNT/polymer interfacial region, a significant enhancement in the material damping capacity is observed. An extensive experimental campaign consisting of monotonic and cyclic tensile tests proved the effectiveness of this novel multi-phase material design.

Abstract (sommario):

A harmonic mistuning concept for bladed disks is analyzed in order to intentionally reduce the forced response of specific modes below their tuned amplitude level. By splitting a mode pair associated with a specific nodal diameter pattern, the lightly damped traveling wave mode of the nominally tuned blisk is superposed with its counter-rotating complement. Consequently, a standing wave is formed in which the former wave train benefits from an increase in aerodynamic damping. Unlike previous analyses of randomly perturbed configurations, the mode-specific stabilization is intentionally promoted through adjusting the harmonic content of the mistuning pattern. Through a re-orientation of the localized mode shapes in relation to the discrete blades, the response is additionally attenuated by an amount of up to 7.6 %. The achievable level of amplitude reduction is analytically predicted based on the properties of the tuned system. Furthermore, the required degree of mistuning for a sufficient separation of a mode pair is derived.

Abstract (sommario):

The present study explores both structural and controller design to attenuate vibration in large membrane structures especially due to low-frequency harmonic excitations. It is very difficult for membrane structures to suppress the low-frequency vibration induced by flexible support structures, because a lightly pre-stressed membrane has extremely low mode frequencies and little damping effect. The present study proposes the use of web-like perimeter cables around a membrane, and the application of simple and lightweight active controllers only along the web cables. This strategy successfully suppresses the membrane vibration when the web-cable configuration is appropriately tailored. Both linear and nonlinear finite-element analyses exhibit a clear tradeoff between structural mass and control efficiency.

Abstract (sommario):

Abstract The localized nonlinear responses of a chain of nonlinear pendulums with time-periodic damping and stiffness coefficients are investigated. The existence conditions and stability of the solitary waves are revisited for the aforementioned system. In essence, the parametrically driven discrete Klein-Gordon equation with time-periodic damping coefficient is converted to a damped parametrically driven discrete nonlinear Schrodinger equation using the method of multiple scales. The numerical simulations show how the stability and characteristics of the solitary waves are modified when the periodically modulated damping coefficient, which is either synchronized or asynchronized with the time-periodic stiffness coefficient, is added. In practice, time-periodic damping coefficient can be treated as a new way to tune the characteristic of the solitons (i.e., required threshold of the soliton activation and the period of oscillations) in the nonlinear periodic structures. This modification may provide some insights towards the control of the energy localization phenomena in nonlinear periodic structures with time-varying coefficients for efficient energy transport/management applications.
