LAMB WAVE INSPECTION: synthesis and conclusion
1st configuration : Structural mode (skin HTS / adhesive / RTM insert)
Fast and quick identification of adhesive defects in samples 2 and 3
Cohesive defect not detectable
Defect representation deformed ⇒ image processing but simple
2nd configuration : Skin mode
Good sensitivity for both adhesive and cohesive defects
lamb wave behaviour more cumbersome on cohesive defect
Peculiar response on adhesive defects of sample 3
- 1st configuration : good for adhesive defect type
- 2nd configuration : good results for both typers of defects to be confirmed for
cohesive one
- Sensitive to sample flatness
