Abstract

The vibration problem of a sandwich plate with a constraining layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The effects of the natural frequencies, static buckling loads, and loss factors on the stability behavior of the sandwich plate are studied in the paper. Rheological property of an ER material, such as viscosity, plasticity, and elasticity may be changed when applying an electric field. The ER core is found to have a significant effect on the stability of the sandwich plate. The modal damper and the natural frequencies for the sandwich plate are calculated for various electric fields. When an electric field is applied, the damping of the system is more effective. In this study, finite element method is used to calculate the stability of the sandwich plate.
