Abstract

Accumulative-double-sided incremental forming (ADSIF) is a newly developed die-less sheet metal forming process, which can form complex freeform sheet metal parts without using any part-shape-specific tooling. This preliminary study investigates the fatigue life of parts formed with ADSIF, on a AA2024-T3 sheet material. It is shown that the material formed with ADSIF has a longer fatigue life than the virgin material. Micrographs of the fracture surface obtained using a scanning electron microscope (SEM) is used to examine the mechanism of failure after the fatigue test. The areas of future work on fatigue life of parts formed with incremental forming are also discussed.
