The economic and environmental benefits of increased fuel economy and reduced emissions are constantly driving the auto sector to reduce the vehicle weight. In this regard, light metals such as Aluminum and Magnesium alloys, for automotive parts are attractive candidates. The major drawback of using light metals is their low formability compared to carbon steels. While their limited formability prevents them for being used in structural parts, advanced manufacturing methods, enable them to be used in outer body applications. Bending is an important and complex deformation mode that occurs during many metal forming operations. The proposed research will combine the latest advancements in the fields of micromechanics; both theoretically and experimentally, to investigate localized deformation phenomena during pure bending for the ultimate goal of improving the formability of light metals in outer body applications.
