Abstract
To explore the formability of larger size pre-stressed aluminum alloy sheet, a novel forming method named the electromagnetic superposed forming (EMSF) is proposed in this paper. The electromagnetic force is incrementally applied to the aluminum alloy sheet which is elastically pre-bended with a 1D curved die matrix. Specimens were formed and their shapes macroscopically curved due to superposition of the many weeny dome-shaped deformations. The feasibility of electromagnetic superposed forming of pre-stressed aluminum alloy sheet has been verified. The results show that the larger the discharge voltage has been given, the bigger deflection will have been obtained.
