Characterization of the formability for aluminum alloy and steel sheets

摘要

In this work, the formabilities of an aluminum and steel sheet samples were assessed both experimentally and theoretically. The forming limit diagram (FLD) and the limiting dome height (LDH) tests were simulated using mathematical models incorporating suitable constitutive equations for the steel and aluminum alloys. Experimental and predicted results were compared and discussed. It was suggested that this type of mathematical modeling can be used to design and optimize forming processes, especially for aluminum alloy sheets.
