Çelik, Alüminyum ve Titanyum Alaşımlarında Hu2003 Akma Kriteri Performansının Araştırılması

Sonlu elemanlar analiz programlarının tahminlerinin doğruluğunu arttırmak için malzeme modelinin doğru seçilmesi gerekmektedir. Çünkü her malzeme için her model iyi tahmin yapamamaktadır. Bu çalışma kapsamında izotropik (von Mises, Tresca) ve anizotropik (Hu2003) akma kriterlerinin çeşitli malzemeler için performansları incelenmiştir. Hu2003 akma kriteri 7 parametre ile tahmin yapabilen bir modeldir. Yapılan incelemeler sonucunda Hu2003 akma kriterinin çok başarılı tahminler yaptığı görülmüştür.
