Fuel efficiency and vehicle crashworthiness are two important issues for modern automotive manufacturing. Current industry standards require aluminum structural components to absorb sufficient crash energy while limiting material microcracking to subcritical fractures. Thus, a successful design for crash-resistant aluminum components must consider microstructural material properties, detailed material failure mechanisms as well as the product and process parameters that determine them. This research projects is a joint research effort between the University and an industrial partner to develop improved manufacturing processes for the production of extruded aluminum components with superior properties for automotive crashworthiness. This collaborative research project has a balance between theory and experiment, and will provide valuable findings for the automotive manufacturing and aluminum manufacturing industries.

燃油效率和车辆耐撞性是现代汽车制造的两个重要问题。 当前的行业标准要求铝结构部件吸收足够的碰撞能量，同时将材料微裂纹限制为亚临界断裂。因此，防撞铝部件的成功设计必须考虑微观结构材料特性、详细的材料失效机制以及决定它们的产品和工艺参数。 该研究项目是大学与工业合作伙伴之间的联合研究成果，旨在开发改进的制造工艺，用于生产具有卓越汽车防撞性能的挤压铝部件。 该合作研究项目在理论与实验之间取得了平衡，将为汽车制造和铝制造行业提供有价值的发现。
