Uniform stability in structural acoustic models with flexible curved walls
The aim of this paper is twofold. First, we develop an explicit extension of the Kirchhoff model for thin shells, based on the model developed by Michel Delfour and Jean-Paul Zolésio. This model relies heavily on the oriented distance function which describes the geometry. Once this model is established, we investigate the uniform stability of a structural acoustic model with structural damping. The result no longer requires that the active wall be a plate, It can be virtually any shell, provided that the shell is thin enough to accommodate the curvatures. © 2002 Elsevier Science (USA).
