| Abstract Scope |
A new test method for sheet metal deformation, Tension under Cyclic Bending and Compression (TCBC), is developed in this study. The TCBC method is capable of testing material deformation under tension, bending and compression with cyclic loading. The effect of each deformation mode can be independently controlled by adjusting corresponding parameters. A TCBC test rig is designed and manufactured and an aluminium alloy is tested under four deformation modes: simple tension, tension under cyclic bending, tension under cyclic compression, and tension under cyclic bending and compression. The maximum elongation and fracture occurrence of the tested specimen under different deformation modes are compared. It has been found that the maximum elongation increases significantly under TCBC condition due to strengthened localised plastic deformation which delays the fracture. The new TCBC method can be used for testing material formability in incremental sheet forming processes, such as single point and double side incremental forming. |
