Alüminyum 2024 T-3 plakadaki hasar boyutunun lamb dalgası ile tespiti

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.
