Abstract:
1. A sonic resonator system which is used to apply a power pulse in the form of a rarefaction wave at a selected location within a composite structure, wherein said system comprises: a computer containing software algorithms for signal reconstruction and a wave form generator; a digital-to-analog converter which is in communication with said wave form generator; a power amplifier; a sonic resonator assembly which transmits sonic energy into said composite structure, where said sonic energy includes a power pulse of a wide-bandwidth rarefaction wave generated using input from said wave form generator; and a removable calibration sensor which enables said resonator system to be calibrated to work in combination with a particular composite material, and wherein said calibration sensor is located in series after said sonic resonator assembly and after a location at which a sample of composite material is placed between said sonic resonator assembly and said calibration sensor, for purposes of calibration of said sonic resonator system.
