预计阅读时间：12 分钟Aug 01, 2005 In the aerospace industry stretch forming is often used to produce skin parts. During stretch forming a sheet is clamped at two sides and stretched over a die, such that the sheet gets the shape of the die. However for complex shapes it is necessary to use expensive intermediate heat-treatments in order to avoid Lüders lines and still achieve large deformations.
