Effect of Pre-Tension and Orientation on the Springback Behavior of the Sheet Brass 65-35

One of the most important phenomenon that occurs in sheet metal forming processes is the spring-back, which causes several geometrical alterations in the parts. The accurate prediction of springback after bending unloading is the key to the tool design, operation control, and precision estimate con...
