Öğe Numerical investigation of fatigue behaviors of non-patched and patched aluminum pipes(Hibetullah KILIÇ, 2021-06-01) Adin, Hamit; Yıldız, Bilal; Adin, Mehmet ŞükrüIn this study, the fatigue behaviors of non-patched and patched aluminum pipes were investigated numerically. The Finite Element Method was used for fatigue analysis in the study. Finite Element Method was implemented with Ansys Workbench (15.0) program. Al 6063 type aluminum pipe, DP-460 type adhesive and [0/90]2 reinforced angled glass-epoxy composite patch material were used in the analyzes. As a result of the numerical study, it was observed that patch size is an effective parameter in fatigue strength and that quarter-circle and semi-circular composite patches increase the fatigue life. It was also observed in the analyzes that the quarter-circle patched aluminum pipes achieved higher fatigue strength.Öğe Numerical investigation of fatigue behavior of non-patched and patched aluminum/composite plates(Ahmet ÇALIK, 2021-12-20) Adin, Hamit; Sağlam, Zeyni; Adin, Mehmet ŞükrüIn this study, the fatigue behavior of composite patched and non-patched Al 5083 aluminum plates was numerically investigated. Al 5083 Aluminum plates with semi-circular notched (2, 3 and 4 mm long cracked) and "V" notched (30°, 45° and 60° angled) were used in the analyzes. Mechanical properties of Al 5083 Aluminum plate, DP460 type adhesive of produced by 3M and [0°]8 glass fiber reinforced composite patch material was used for the study. The Finite Element Method was applied for numerical study. Numerical analyzes were performed with the Ansys version 15.0 Workbench Package program. As a result of the numerical study, the highest fatigue life (1593.2 N) is seen on the 30° angled "V" notched and patched specimen. However, the fatigue life in non-patched specimen (30° angled "V" notched) was found to be 277.69 N. Thus, the study revealed that the composite patch's contribution is very important.Öğe Partikül takviyeli yapıştırıcılarla üretilmiş jute kompozit malzemelerin mekanik özelliklerinin deneysel olarak belirlenmesi(Batman Üniversitesi, 2018-05) Adin, Mehmet Şükrü; Ergün, Raşit Koray; Adin, HamitBu çalışmada jute tipi kumaşlardan üretilmiş kompozit malzemelerin mekanik özellikleri incelenmiştir. Kompozit malzemeler, yapıştırıcı malzemesi kullanılarak 11 katman olacak şekilde üretilmiş olup verilen ölçü ve değerlere göre kesilmiştir. Elde edilen numuneler çekme deneyine tabi tutulmuştur. Verilere göre alüminyum tozun kompozit numunede daha sağlam bir yapı oluşturduğu gözlemlenmiştir. Deneysel olarak elde edilen sonuçlar tablo ve grafik olarak sunulmuştur. Sonuç olarak; partikül katkılı yapıştırıcı kullanılmasıyla elde edilen kompozit malzemelerin çekme hasar yükünün arttığı görülmüştür.
