Study on the Scattering of Elastic Waves for the Nondestructive Evaluation of Piezoelectric Composites

摘要

The wave function expansion method is engaged for the theoretical derivations to study the effect of material parameters perturbations on the resonance acoustic scattering behavior of 1-3 piezoelectric composites. Numerical examples are provided to verify the effectiveness of the analysis. Results obtained are meaningful for the non-destructive evaluation of 1-3 piezoelectric composites.
