Bu
çalışmada, hasar tespiti ve yapısal durum izleme için Alüminyum 2024 T-3
plakası üzerinde oluşturulan 2 ile 5 cm arası kesikler Lamb dalgaları ile
incelenmiş ve Lamb dalgalarının simetrik ve asimetrik modlarının
karşılaştırılması yapılmıştır. Toplanan yüzey frekans cevaplarının zarfları
Hilbert dönüşümü ile elde edilmiş ve her bir hasarın zayıflama miktarı yüzdelik
olarak gösterilmiştir. Elde edilen sonuçlar, her iki Lamb dalga modunun
Alüminyum 2024 T-3 plakada oluşturulan kesik boyutlarının araştırılmasında
kullanılabileceğini göstermektedir.

Anahtar Kelimeler

Lamb dalgası, Hilbert dönüşümü, Yapısal durum izleme
