Viscoelastic materials are commonly used as constrained thin layers in order to reduce the noise radiated by vibrating structures. The optimal design and placement of these viscoelastic interfaces requires an eﬃcient characterization and modeling strategy. This work present an original automatic procedure to build the master curves of viscoelastic materials consistent with the causality principal, and interface ﬁnite elements for the modeling of thin constrained layers.
