Evaluation of the Dynamic Characteristics of Beams with Magneto-Rheological Interlayers

We analyze the dynamic characteristics of layered plates formed by rigid outer layers and inner layers with magneto-rheological properties. We estimate the influence of magnetic field on the frequency and loss factor for different magneto-rheological and rigid outer layers of materials. The applied improved theoretical model takes into account the deformations of each layer, including the transverse-shear and transverse normal deformations, as well as the nonlinear variations of displacements across the thickness of the plate.
