- Abstract
By the results of experimental measurements of the Lamb wave’s amplitude at the fundamental frequency and its second and third harmonics, the spatial distributions of the quadratic and cubic nonlinear acoustic parameters in a thin circular plate of D16 polycrystalline aluminum alloy with defects were calculated. The correlation between these distributions and defect positions in the plate was determined.
