Nettetthat the combined Swift/Hockett-Sherby strain-hardening model is most suitable to describe aluminum strain hardening behavior. 1. Introduction . Aluminum alloys have been increasingly used in the automotive industry as the favoured solution for vehicle weight savings. Since aluminum alloys are typically less formable than steels, it is often a
