Abstract
Bu çalışmada endüstriyel boyutta alüminyum
ekstrüzyon işlemi nümerik ve deneysel olarak incelenmiştir. Proses
parametreleri ve kalıp geometrisi ASAŞ Alüminyum tarafından sağlanmış ve model
Sonlu Elemanlar ve Sonlu Hacimler yöntemlerine dayalı farklı yazılım
paketlerinde hazırlanmıştır. Gerekli malzeme karakterizasyonu tek eksenli basma
deneyiyle elde edilmiş ve bu test için yüksek sıcaklıklarda da kullanılabilen
bir test düzeneği geliştirilip imal edilmiştir. Ölçülen kuvvet-yer değiştirme
ve çıkış sıcaklığı ile ilgili grafikler nümerik sonuçlarla karşılaştırılmıştır.
İlaveten Sonlu Elemanlar ve Sonlu Hacimler yöntemleri de kendi içlerinde
karşılaştırılmışlardır. Bu sonuçlar göstermiştir ki, doğru malzeme
karakterizasyonuyla Sonlu Elemanlar yöntemi ile elde edilen sonuçlar gerçek
işlemde ölçülen değerlere yakın çıkmaktadır.
