    Abstract : In this thesis, a Nonlinear Acoustic Technique (NAT) has been used to do a non-destructive quality assurance of plasticized polyvinyl chloride (PVC) specimens. The response of the specimen to an ultrasonic wave is analyzed in order to characterize its material properties. READ MORE

  5. 4. Investigation og Nonlinear Acoustical Properties of Perforated Plate Samples and Samples of Aircraft Engine Liners

    University essay from KTH/Farkost och flyg

    Author : Daniel Pimenov; [2011]
    Keywords : ;

    Abstract : Five samples, three perforated plates and two more realistic samples used in aircraft engine liners have been investigated. All the samples when exposed to high amplitude sound waves show nonlinear acoustic behavior which depends on acoustic velocity at the plate position. READ MORE
