In this article a dynamic analysis on structures featured with special materials is performed. The structure consists of a curved sandwich beam with ceramic-metallic materials whose elastic behavior can be modified by influence of electro-magnetic fields. The interest for this type of magneto-electro-elastic (MEE) couplings is associated to the construction of imbedded sensors and actuators in high performance aero spatial structures. The problem of coupled elastic, electric and magnetic fields is briefly explained and the 3D motion equations for curved members are introduced. A finite element approach is employed in order to calculate natural frequencies and forced vibrations of sandwiched MEE curved beams.
