... of strains in this region is essential for calculating bend allowance. In the elastoplastic zone (regions A–E), a part of the sheet undergoes elastic deformation while the remaining part undergoes plastic deformation. The elastic recovery after unloading (punch withdrawn) causes redistribution...

... of dynamic behavior on speed range is then investigated and determined with accuracy. Dedicated experiments are carried out in order to confirm model results. They show that dynamic effects due to high rotational speed and elastic deformations, such as gyroscopic coupling and spin softening, have...

... to reveal their effects upon the WME. The underlying mechanism is that source errors lead to the workpiece position error (WPE), the workpiece elastic deformations (WED), and the inconsistent datum error (IDE), and all of them will contribute together to the WME. Here, the IDE refers to the dimension...

... sources of error are considered: fixture geometric error and elastic deformation of the fixture and workpiece due to fixturing forces. The workpiece location error is predicted by modeling the process of part loading (given fixture geometric variations) and clamping (given deformations at the contact...
