The problem of passive vibration control of plane structures by the use of viscoelastic material coating is discussed in this paper. It is well known that the structures used in the aerospace industry are often exposed to a wide range of operating temperatures. Consideration has been given to the fact that the characteristics of the viscoelastic materials are sensitive to these variations. It is demonstrated that, among the operating parameters, ambient temperature has a crucial effect on control performance. Furthermore, to lighten the structure as much as possible, the option of partial coating is investigated. An optimization algorithm giving the optimal use of the material is implemented. The shape of the coating and the locations where it should be applied are thus known.
