Abstract
In this research work, the mechanical behavior of a hybrid sandwich beam in magnetorheological elastomer loaded with 40% ferromagnetic particles has been studied. A finite element model has been developed for the three layers. The sandwich beam is modeled using transverse displacement at core layer. The finite element model of the damped three-layer beam is assumed that every layer has the same transverse displacement, and it is derived using the Golla–hughes–McTavish’s principle. Different specimens have been modeled by varying the magnetic field intensity and static force and studied under the clamped-free and cantilever boundary conditions for modal analysis. Results show the influence of MRE adaptive stiffness and the loss factor in the static behavior of the sandwich studied. The structure proposed can be directly applied to civil engineering, for example, aeronautics, aerospace, and building foundations.
