Prediction of Wrinkling by Solid-Shell Element in Sheet Metal Forming
Sac Metal Şekillendirmede Katı-Kabuk Elemanı ile Buruşmanın Tahmini

Ahmet Zafer ŞENALP [1]


In this study, the explicit analyses of a forming operation to produce a standard rail part [9, 18] are performed by solid-shell, shell, and solid elements within Ansys Workbench Ls-Dyna environment. Although the results do not exactly fit with the experimentally obtained part, it is shown that the solid-shell element yields the best result in terms of wrinkling. The solution obtained by solid-shell element is in good accordance with the result obtained by Neto et al.[18]. The shell and solid elements cannot predict the instability wrinkling behavior as solid-shell element does. Also, it can be deduced that solid-shell element is more computationally effective than shell element.
Sac şekillendirme işlemlerinde buruşma kusurların tahmininde sonlu elemanlar yöntemi ve kabuk elemanları kullanılmaktadır. Bu yöntem, yüzey modeli oluşturmada zaman kaybına ve yanlış modellemeden kaynaklanan olası temas hatalarına eğilimlidir. Bu çalışma Ansys Workbench Ls-Dyna ortamında sac parçalar için metal şekillendirme işlemlerinde katı-kabuk elemanların kullanımını incelemektedir. Buruşmaya eğilimli standart bir test parçası için katı-kabuk ağlar oluşturulmuştur. Sac için DP600 malzemesi kullanılmıştır. Şekillendirme araçları arasındaki sürtünme davranışı dikkate alınmıştır. Çeşitli sınır koşulları test edilmiştir. Analiz sonuçları, kabuk analizi sonuçları ve daha önce elde edilen deneysel sonuçlarla karşılaştırılmıştır. Sonuçlar, katı-kabuk eleman kullanımının, kabuk ve katı elemanlara göre buruşma davranışı açısından daha doğru sonuçlar verdiğini göstermektedir.
