Investigations on the Formability of Incremental Punching Process
It was reported that the incremental sheet metal forming (ISMF) produces larger deformations as compared to the conventional forming processes.

Summary: | It was reported that the incremental sheet metal forming (ISMF) produces larger deformations as compared to the conventional forming processes. We developed a new ISMF method based on incremental punching. In this study, a theoretical method based on M-K analysis is presented to determine the forming limit curve (FLC) in this forming process and it has been integrated to our in-house FEM program. Also, a ductile fracture model is used for comparing of the forming limit of the process. A numerical example is then given and verified by experiments. The results indicate that the proposed method provides an available approach to determine the FLC of incremental punching process. |
