Vibration Characteristic Analysis of Polar Orthotropic Sandwich Annular Plate with Tunable MR Elastomer Treatment

Abstract

Vibration analysis of polar orthotropic sandwich annular plate with magnetorheological (MR) elastomer is considered. The effects of thickness of the MR elastomer, applied magnetic fields on the sandwich system are discussed. The characteristics of the sandwich plate system can be controlled and changed by the applied magnetic fields. The core layer of MR elastomer has significant effects on the damping behavior of the sandwich plate system according to the numerical results.
