The design and the optimization of structures with constrained layer damping (CLD) treatment requires an efficient numerical tool. The frame of this work is the modelling of thin constrained viscoelastic layers embedded in a massive structure meshed in 3D. A zero-thickness interface finite element is developed in order to model this viscoelastic layer, which enables to modify both its placement and thickness without remeshing the whole structure.
