Bending and Springback of Aluminum Alloy Sheet and Plate

Source

A practical method was developed to predict the minimum bend radius and the amount of springback of aluminum alloy sheet and plate. Analytical equations describing the mechanics of bending were used and were correlated with extensive 90-deg air bend test results of alloys 2024-T3, 3003-H14, 5052-H32, 5083-O, 6061-O, 6061-T4, 6061-T6, and 7475-T6. The method utilizes the fracture strain obtained from a bend test or tension test in the minimum radius prediction and the mechanical properties obtained from a tension test in the springback prediction.
