New Approach for Wrinkle Prediction in Deep Drawing Process
Keyword(s):
Due to the extensive use of thin sheet metals to reduce weight of car bodies, wrinkling is becoming a more common and one of the most undesirable defects in sheet metal forming processes. Recent experiments at the Institute for Metal Forming Technology (IFU), University of Stuttgart, indicated that the buckling test using modified specimens can enhance accuracy for the predication of wrinkling [1]. In this paper a new method to predict the onset of the wrinkling will be introduced, and results of this test will be compared with real deep drawing parts. The wrinkle heights will be considered an evaluated regarding to results obtained by an optical measurement system.
