摘要

The dynamic stability problem of a sandwich beam with a constrained layer and an electrorheological fluid core subjected to an axial dynamic force are studied. Rheological properties of an electrorheological material, such as viscosity, plasticity, and elasticity may be changed by applying an electric field. Effects of the natural frequencies, static buckling loads and loss factors on the dynamic stability behavior of the sandwich beam are investigated. The finite element method and the harmonic balance method are used to calculate the instability regions of the sandwich beam. The electrorheological core is found to have a significant effect on the dynamic stability regions.
