Investigation of Springback Behavior of DP Series Sheet Metal in Bending Process

Abstract

Abstract-In the study, the springback behavior took place during V bending of DP series Sheet metals having different quality was experimentally investigated. For this purpose, sheet metal having quality of DP800 and DP600 with size of 45x90 mm thickness of 1, 1.5 and 2 mm and V bending die having 60, 90, and 120 o angles were used. The data obtained from results of experimental studies was graphically represented and the evaluated.

Düşen Ağırlıklı Düşük Hız Balistik Testi ve Farklı Metal Türlerindeki Hasarı

“…The springback force is mostly determined by stored elastic behaviour during the sheet metal forming or high modulus of elasticity of new type of steels such as DC04 steels [26]. The correlation between material properties and impact response given in Table 2 as a measure of correlation by Elasticity modulus (E), the work hardening coefficient (n) and strength coefficient (K) as given in Hollomon's equation.…”

Analysis of The Effect of The Bending Angle Position on Springback in Offset Bending Dies by Using Finite Element Method

“…Yapılan bükme çalışmaları incelendiğinde birçok araştırmacı, V, L, U bükme işlemi üzerine malzeme ve bükme işlem parametrelerinin etkilerini hem deneysel hem de sonlu elemanlar analizi yöntemini kullanarak araştırmışlardır [6][7][8][9][10][11]. Ancak yapılan araştırmalar neticesinde ofset bükme üzerine çok az sayıda çalışmaya rastlanmıştır.…”
