Paper Abstract

The paper deals with the nonlinear vibro-acoustic modulation technique (VAM) used for nondestructive damage detection in composites. In its original form the technique allows only for the determination of the presence of damage in a structure. This paper presents an enhancement of the technique that allows also for the determination of damage location. Experimental testing of the proposed procedure is performed on carbon fiber/epoxy laminated composite plates with barely visible impact damage that was generated in an impact test. Shearography was used to verify damage location. Piezoceramic actuators are used for vibration excitation and a scanning laser vibrometer is used for data acquisition.
