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.

提高燃油经济性和减少排放的经济和环境效益不断推动汽车行业减轻车辆重量。在这方面，用于汽车部件的轻金属如铝和镁合金是有吸引力的候选者。使用轻金属的主要缺点是与碳钢相比它们的可成形性低。虽然它们有限的可成形性使它们不能用于结构部件，但先进的制造方法使它们能够用于外体应用。弯曲是金属成形过程中一种重要而复杂的变形方式。拟议的研究将联合收割机在微观力学领域的最新进展，无论是理论和实验，研究局部化的变形现象，在纯弯曲的最终目标，提高轻金属的成形性在外部机构的应用。
