✦ Synopsis

Free vibrations of rectangular plates supported with intermediate viscoelastic line supports which are placed in a row parallel to one of the edges of the plate are discussed in this paper. In the analysis, the intermediate viscoelastic line supports are considered as massless line springs. On the assumption that the edges of the plate normal to the line supports are simply supported, the frequency equation is derived by using a transfer matrix method. The effects of the number and the stiffness of the viscoelastic line supports on the damped natural frequency and logarithmic decrement of the system are investigated.
