Nonlinear Acoustic Imaging of Structural Damages in Laminated Composites

Abstract

The paper describes the application of nonlinear acoustic techniques recently reported in scientific literature for imaging of structural damage in a laminated composite plate. The techniques that have been considered include the local defect resonance technique and the second harmonic imaging technique. The tests are performed on a carbon fiber/epoxy laminated composite plate with barely visible impact damage that was generated in an impact test. The extent of damage is characterized by vibrothermography prior to nonlinear acoustic tests. The paper discusses theoretical background and experimental setup for each measurement technique.
