flexible-die bulging In order to verify the reliability of the developed CDSB-FEM-EFGM code based on the above theory, the simulation of sheet flexible-die bulging of Al1060 sheet is conducted... of 50.0 mm, and is discretized with 456 nodes. The elastic modulus and Poisson ratio of the elastic flexible-die are 10.0 MPa and 0.49, respectively. The Al1060 sheet is discretized with 33 two-node......
, Al1100 and Al1060 deformed by ECAP up to different number of passes [35-38]. Interestingly, it was noted that the values of the 0.2% proof strength were in a relatively good agreement... of the elongation variation with the increase of the ECAP number of passes was observed in the case of Al1080, Al1100 and Al1060 [3,36-38]. The drastic decrease of the elongation in the initial pass can......
