Acoustic Emission and Digital Image Correlation-Based Study for Early Damage Identification in Sandwich Structures
Authors: Contents:- Monitoring the quality of complex sandwich structures is difficult with common testing techniques for accessibility reasons
- A novel approach to solve this issue is enabled by acoustic monitoring in the ultrasound regime with the Optical Microphone
- The results from acoustic monitoring were compared to findings obtained with digital image correlation
- It could be shown that early identification of structural damage is possible with the Optical Microphone
