  3. 2. Crack Detection using Non-linear and Dissipative Acoustics

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Daniel Carldén; Daniel Thuresson; [1998]
    Keywords : Non-linear acoustics; Non-linear parameter; Burger s equation; Bessel-Fubini; Fay; Mendousse; Hedberg; Non-destructive testing NDT ; Non-destructive Evaluation NDE ; crack detection.;

    Abstract : A theoretical model for identification of acoustical non-linearity using Burger's equation was implemented in a MATLAB program. The program identified both the non-linearity parameter and the distance from the signal source. Tests were performed in order to verify the theories. READ MORE
