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)
