Examination of acoustic insulation of composite metamaterials with negative stiffness elements inclusions
Damping is one of the most important properties of materials, being responsible for increased durability and conmfort of the structures. In this paper the damping enhancement of materials with internal oscillators is examined. Wave Finite Element (WFE) method is used to get the wave propagation of a...

| description | Damping is one of the most important properties of materials, being responsible for increased durability and conmfort of the structures. In this paper the damping enhancement of materials with internal oscillators is examined. Wave Finite Element (WFE) method is used to get the wave propagation of an two-dimensional layered mechanical material having embedded nonlinear internal oscillators acting as negative stiffness element. The acoustic properties of the panel are studied in a Statistical Energy Analysis (SEA) scheme. |
