Parametric probabilistic analysis in the uncertain dynamics of magneto-electro-elastic beams resting on elastic foundations

Abstract:

In this paper, the authors are concerned with the dynamic behaviour of magneto-electro-elastic (MEE) beams mounted on elastic foundations. The MEE beams are a type of composite structures that can be employed as imbedded subsystem in high performance aero spatial structures, control of motion and attenuation of vibrations, energy harvesting, etc. The structure consists of a sandwich beam with ceramic/metallic materials whose elastic behavior can be modified by influence of electro-magnetic fields. Although most of the research work related to the mechanics of MEE structures was done for dynamics [1] and statics [2], it is remarkable the scarcity of papers analyzing the uncertainty propagation in the dynamics of a MEE beam structure.
