Energy exchange between nonlinear oscillators: An entropy foundation
In the field of vibrations of complex structures, energy methods like SEA and a series of mid-frequency methods, represent an important resource for computational analysis. All these methods are based in general on a linear formulation of the elastic problem. However, when nonlinearities are present, for example related to clearance or stiffening of joints, these methods, in principle, cannot be applied. This paper, on the basis of a theory presented recently by one of the authors, proposes a foundation of a new energy method able to deal with nonlinearities when studying the energy exchange between subsystems. The idea relies on the concept of a thermodynamic vibroacoustic temperature, that can be directly defined when introducing the entropy of a vibrating structure. The theory is introduced in general, and examples of calculation of the power flow between nonlinear resonators are presented introducing stiffening and clearences for systems with many degrees of freedom

Les Trois Ordres au féminin : A faut esperer qu'eu se jeu la Finira bentot
Eau-forte en couleurs, 27 x 17 cmComme il est exprimĂ© au bas de la version masculine de ces gravures populaires naĂŻves de qualitĂ© graphique assez mĂ©diocre, et qui ont Ă©tĂ© largement diffusĂ©es, le peuple, en cette fin du XVIII e siècle, semble las de l'inĂ©galitĂ© devant la loi et l'impĂ´t. Les cahiers de dolĂ©ances de 1789 exprimaient un ardent loyalisme au roi et un profond dĂ©sir de rĂ©forme : revendication Ă©galitaire, dĂ©nonciation des privilèges, appel aux droits naturels mais en des termes qui ne prĂ©sageaient en rien du dĂ©roulement de la RĂ©volution, ni de l'œuvre lĂ©gislative de l'AssemblĂ©e constituante. En 1788, quand, devant les notables, Necker dĂ©nonce l'exclusion "de la vie publique, de toute une classe d'hommes unie Ă la prospĂ©ritĂ© de l'Ă©tat" et que Louis XVI accorde au Tiers État autant de dĂ©putĂ©s que la noblesse et le clergĂ© rĂ©unis, on peut percevoir l'Ă©mergence d'une force politique qui Ă©mane du peuple. Sur tout le territoire national souffle un vent d'espoir de changement, de rĂ©conciliation, de concorde qui s'exprime par la diffusion en grand nombre d'estampes Ă caractère populaire ou plus sophistiquĂ©, mais toujours Ă connotation philosophique ou symbolique.tĂ©lĂ©chargeabl
