| Abstract: | The aim of this paper is to get a good approximation of damping properties of viscoelastic damped sandwich structures. Firstly we will compare the classical models based on the kinematics of Kirchhoff-Love, Mindlin, Reddy or Touratier. In the second stage these models are used to establish the zig-zag models which describe a piecewise continuous displacement field. These models are compared in the static and the dynamic fields. In all cases the Finite-Element-based solution is considered as reference. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) |
