  3. 17. Nonlinear Non-Destructive Testing of ship hull composites

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Johan Larsson; Daniel Pettersson; [2004]
    Keywords : Non-contact testing; Non-Destructive Testing; Ultrasonic testing; Nonlinear Wave Modulation Spectroscopy; Sound velocity; Resonance.;

    Abstract : Further development of an existing nonlinear ultrasound Non-Destructive Testing method is performed. The Nonlinear Wave Modulation Spectroscopy method is developed into an automated non-contact testing method. The method detects nonlinearities, such as cracks and delaminations, in a test object.

  4. 18. Non-linear ultrasound investigation of extended plates

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Rikard Gunnarsson; [2003]
    Keywords : Ultrasonic NDT; Non-linear acoustic testing; Non-linear non-destructive testing; Non-linear Wave Modulation Spectroscopy; Non-linear Elastic Wave Spectroscopy; Micro crack detection;

    Abstract : A non-linear ultrasound non-destructive testing method called Non-linear Wave Modulation Spectroscopy is studied. The method shows the non-linearity of the test specimen and can in that way detect cracks. It is at present non-localizing. READ MORE

  5. 19. Crack detection using Non- Linear Wave Modulation Spectroscopy

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Kristofer Larsson; Andreas Silverbris; [2003]
    Keywords : NWMS; Rotor blade; Micro crack; Excel; Theoretical derivation; Experimental implification;

    Abstract : This report comprises an investigation of the non-linear ultrasonic crack detection method; Non-Linear Wave Modulation Spectroscopy, NWMS. Cracks in test objects were according to the NWMS method detected through their non-linearity. READ MORE
