Dördüncü Dereceden Polinom Türü Bir Akma Fonksiyonu Kullanarak AISI 304 Paslanmaz Çelik Sacın Anizotropik Davranışının Modellenmesi

Year 2020, Volume: 18 Issue: 1, 1 - 8, 19.09.2020

Abstract

Bu çalışmada ortotropik, kuadratik olmayan, homojen polinom türü bir akma kriteri tanımlanmış ve açık zaman integrasyon yöntemi ile kriterin sac şekillendirme analizlerinde kullanılabilmesi için sonlu eleman uygulaması sunulmuştur. Uygulamanın performansı, ilk olarak AISI (304) paslanmaz çelik çelik sacın çekme testi simulasyonlarıyla değerlendirilmiş olup, akma gerilmesi oranı ve anizotropi katsayısının yöne bağlı değişimleri tahmin edilmiştir. Ardından, dikdörtgen bir kabın derin çekme simulasyonu gerçekleştirilmiş ve hesaplanan kalınlık ve taban geometri profili ölçüm sonuçlarıyla değerlendirilmiştir. Her iki deformasyon prosesi için yapılan karşılaştırmalar, dördüncü derece polinom türü akma kriterinin AISI (304) paslanmaz çelik sacın anizotropik davranışını doğru bir şekilde tanımlayabildiğini göstermiştir.
