摘要： Superplastic forming or gas forming is favorable method for the manufacture of sheet metal for making airplane skin panels. However, a major challenge in applying this method is controlling the thickness distribution in the formed product. Here, we explore a hot-bending-assisted process for gas forming of a deep trough with a complex shape for use in airplane wings. We propose the deliberate arrangement of wrinkles to achieve uniform thickness distribution. Because full-scale experiments are costly, sub-scale specimens are preferred for collecting experimental data. In linking sub-scale data to full-scale manufacturing, the size effect on wrinkle formation sites is important. The cause of the pre-form contour and larger-size specimen could be the greater variations in contour modes due to plastic buckling during the pre-forming stage. 其他題名： Int J Adv Manuf Technol 出版者： London: Springer London 出版日期： 2016-10-01 出處： International journal of advanced manufacturing technology, 2016-10, Vol.86 (9-12), p.2747-2752 資源來源： EBSCOhost Academic Search Premier 版權： Springer-Verlag London 2016 版權： Copyright Springer Science & Business Media 2016 版權： The International Journal of Advanced Manufacturing Technology is a copyright of Springer, (2016).
