Abstract
The invention concerns a damping device having improved damping properties, including a lower damping viscoelastic layer made from a viscoelastic material affixed to a structural element, and an upper stress constraining layer located above the lower viscoelastic layer on the side opposite of the structural element. The upper stress constraining layer is a composite stress constraining layer having a stress constraining element embedded in a damping material. This stress constraining element can be a clothlike element selected from a knit, a woven or unwoven fabric, or can be prepared from a grid of bundles of strands linked together through welding or gluing.
