Abstract
A laminate material for damping a vibrational mode of a structure is provided, the laminate material comprising a viscoelastic layer and a stiff constrained layer adhered to the viscoelastic layer, wherein the viscoelastic layer is elastomer based and the constrained layer is made of steel, galvanized steel or aluminum. Furthermore, a damping arrangement for damping at least one vibrational mode of a structure is provided, comprising a laminate material having a soft viscoelastic layer and a stiff constrained layer, wherein the laminate material is provided in the form of at least two longish stripes, the soft viscoelastic layer of the at least two stripes being adhered to a surface of the structure, and the at least two stripes being oriented at an angle of 0° to 180°, preferably 90°, with respect to each other.
