Experimental Verification of Contact Acoustic Nonlinearity at Rough Contact Interfaces

Experimental Verification of Contact Acoustic Nonlinearity at Rough Contact Interfaces

When a longitudinal wave passes through a contact interface, second harmonic components are generated due to contact acoustic nonlinearity (CAN). The magnitude of the generated second harmonic is related to the contact state of the interface, of which a model has been developed using linear and nonl...
