Non-destructive holographic vibrometric testing of the adhesive joint in metal-polymer laminates (Rapid communication)

Abstract

The possibility to detect defects in polyamide-aluminum composites with pure adhesive connection using holographic vibrometric non-destructive testing (NDT) was investigated. Clear differences could be observed in the phase of vibration patterns and amplitudes, registered with nanometric resolution, between a correct and a defective adhesive connection.
