Abstract :
In the present study a sandwich plate, of rectangular form, with magnetorheological (MR) fluid core is investigated. The plate consists of two outer layers made of aluminium and an MR fluid layer in between. The plate edges are clamped. It was assumed that the aluminium layers are pure elastic. The energy is dissipated in MR fluid layer. Additional assumptions concerning displacements, deformations and stresses are introduced in calculations. The active segment of MR fluid layer is placed in various parts of plate. The optimal positions of active segment for selected modes of vibration are determined.
