Bu çalışmada son yıllarda
otomotiv endüstrisindeki kullanımında artış görülen yüksek mukavemetli DP 800
sac malzemelerin mekanik özelliklerinin deformasyon hızına bağlı değişimi ve
geri esneme davranışları incelenmiştir. Aynı zamanda malzemenin şekillendirme
işleminin ETA-Dynaform 5.5 sonlu elemanlar yazılımında simülasyonları yapılmış,
malzemede elde edilen geri esneme miktarları deneysel sonuçlarla
karşılaştırılmıştır. Malzemenin geri esneme davranışının, artan deformasyon
hızına bağlı olarak çok az miktarda azaldığı ve sac genişliğinin geri esneme
üzerinde önemli bir etkisinin olmadığı tespit edilmiştir. Simülasyon sonuçları
ile deneysel veriler arasında farklılıklar olduğu tespit edilmiştir.
