Multiscale modelling of instabilities and localized deformation phenomena in aluminum and magnesium alloys during pure bending

提高燃油经济性和减少排放带来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，用于汽车零部件的铝和镁合金等轻金属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，它们的成形性较低。虽然它们有限的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壳应用。弯曲是一种重要而复杂的变形方式，在许多金属成形过程中都会发生。这项拟议的研究将结合微观力学领域的最新进展，从理论和实验两方面研究纯弯曲过程中的局部变形现象，最终目标是改善轻金属在外壳应用中的成形性。

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.
