Harmonic generation measurements in unidirectional graphite/epoxy composites
Abstract
A new quantitative technique using piezoelectric transducers bonded directly to specimens has been developed for measuring the nonlinearity of composites. The use of the technique to calculate nine third-order elastic coefficients for a transversely isotropic composite is reported.
