Abstract

Within the scope of this study, the effects of yield and hardening criteria used in forming simulations on part geometric dimensions were investigated. As material 0.8 mm thick DC04 material is used. In the study, the results were compared using the Hill-48 and Barlat-91 yield criteria and experimental flow curve, Hockett-Sherby, Ludwig and Hollomon flow curve models. The studies were carried out in Simufact Sheet Metal Form software. Although all the models studied because of dimensional evaluations estimated within tolerance values, the model in which the experimental data were used with Hill-48 gave the closest results to the nominal dimensions.

Abstract

Bu çalışma kapsamında, şekillendirme simülasyonlarında kullanılan akma ve pekleşme kriterlerinin parça geometrik boyutlarına etkisi incelenmiştir. Malzeme olarak 0.8 mm kalınlığındaki DC04 malzemesi kullanılmıştır. Çalışmada Hill-48 ve Barlat-91 akma kriterleri ile deneysel akma eğrisi, Hockett-Sherby, Ludwig ve Hollomon akma eğrisi modelleri kullanılarak sonuçlar karşılaştırılmıştır. Çalışmalar Simufact Sheet Metal Form yazılımda gerçekleştirilmiştir. Boyutsal değerlendirmeler neticesinde çalışılan bütün modeller her ne kadar tolerans değerleri içerisinde tahmin etmiş olsa da deneysel verilerinin Hill-48 ile kullanıldığı model nominal boyutlara en yakın sonuçları vermiştir.
