Abstract

Bu çalışmada,
St37 çeliğine Charpy darbe testi uygulayarak malzemenin darbe absorbe enerjisi
incelenmiştir. Ortasında dairesel delik bulunan ve deliksiz olmak üzere iki
farklı numune modeli kullanılmıştır. Deneysel prosedürde, numuneler 50x20x2 mm boyutlarında
hazırlandıktan sonra dairesel delik etkisini inceleyebilmek için numune
merkezine 9 mm çapında dairesel delik açılmıştır. Deneyler üniversal Charpy
darbe test cihazında tüm numuneler için üçer kez tekrar edilmiştir. Test
cihazının vurucu kütlesi 6.784 kg olup kapasitesi 49.05 J dür. Sayısal
çalışmada, ANSYS yazılımı ön işlemci olarak, LS-DYNA ise çözücü olarak
kullanılmıştır. St37 çelik malzeme numunesi için, çözücüde Mat 15(Johson-Cook)
malzeme modeli tercih edilmiştir. Vurucu ve mesnet modeli için Mat 20 (Rigid)
malzeme modeli seçilmiştir.

Enerji
sönümleme mekanizması hem deneysel hem de sayısal yöntemlerle analiz edilerek, delikli
ve deliksiz numuneler için karşılaştırılmıştır. Elde edilen verilere göre deliksiz
numunelerin darbe dirençleri, merkezinde 9 mm çapında dairesel delik bulunan
numunelerle kıyaslandığında önemli bir üstünlüğe sahip olduğu gözlemlenmiştir.
Numune kesitinde sürekliliğin bozulmasıyla birlikte darbe sönümleme enerjisinin
deneysel olarak % 46.53 oranında düştüğü tespit edilmiştir. Numunelerin deneysel
çalışmalar sonrasında ölçülen darbe absorbe enerjileri ile sonlu elemanlar
metodu kullanılarak elde edilen sayısal analiz sonuçları karşılaştırılarak grafikler
halinde sunulmuştur. Çalışma sonucunda, sayısal ve deneysel yöntemlerle elde
edilen sonuçlar arasındaki maksimum fark tüm numuneler için %4.62 olarak elde
edilmiştir.
Kullanılan sayısal
darbe test metodunun deneylere gerek kalmadan karmaşık ve farklı geometrilere
sahip numuneler için uygulanabilirliği ortaya çıkmıştır.
