3D Surface Profile Construction and Flaw Detection in a Composite Structure
- 10 Downloads
The nondestructive method of evaluating material properties and structural integrity is built upon ultrasonic scanning, raw data acquisition and processing, coming from an ultrasonic transducer. Commercial software LabVIEW designed by National Instruments Inc. is aimed at processing ultrasonic images. An ultrasonic C-scan image system was developed. This system is capable of constructing a 3D surface profile and detecting flaws inside the composite structure. The technique for nondestructive inspection and geometry estimation is validated experimentally on an aluminum plate with small holes and composite structure with a delamination defect.
