Abstract
A hyperdamping inclusion under constraint with large, broadband frequency damping properties is disclosed. The inclusion includes materials under near-buckling constraint such that fundamental eigenfrequency vanishes at near-buckling.
Claims21
An apparatus, comprising:
- an elastic element including an inner portion and a plurality of structural members extending outward from the inner portion,
- the elastic element disposed within a boundary such that each structural member from the plurality of structural members is compressed between the inner portion and the boundary,
- the elastic element configured to attenuate waves including at least one of acoustic waves or vibrational waves.
An apparatus, comprising:
- an elastic element including a plurality of structural members,
- the elastic element having a first dimension in an unconstrained state,
- the elastic element disposed within a boundary in a constrained state in which the boundary applies an inwardly directed load upon each structural member from the plurality of structural members, the elastic element having a having a second dimension in the constrained state that is less than the first dimension.
A method, comprising:
- forming an elastic element having a plurality of structural members;
- and
- constraining the elastic element such that each structural member from the plurality of structural members is subjected to an inwardly applied load, the elastic element when constrained configured to attenuate waves including at least one of acoustic waves or vibrational waves.
