This Grant Opportunity for Academic Liaison with Industry (GOALI) project in collaboration with Ford Motor Company provides funding to, a) create a fundamental understanding of the mechanism which enhances metal formability during continuous-bending-under-tension and b) to exploit this behavior through innovative manufacturing processes. In order for the industry to take advantage of continuous-bending-under-tension to achieve formability improvements, fundamental knowledge of the underlying phenomena, accurate models to predict material behavior and innovative processing solutions to exploit this effect are required. Two specific materials, DP780 steel and AA6022 aluminum alloy will be investigated in this research. Both of these are of interest and increasingly evaluated for various weight-sensitive applications, but have very different microstructures and are expected to behave differently during continuous-bending-under-tension. The principal investigators and senior personnel have significant and relevant expertise in experimental mechanics, material characterization, microstructural-based and continuum constitutive modeling, process simulations, and sheet metal forming, to assure the success of this research.If successful, the results of this research will benefit society at large by reducing the environmental impact of products such as automobiles and by enabling more aggressive product designs, which will further decrease the weight and cost of components. Also, graduate and undergraduate students will benefit from the industrial focus of this project and the fact that the results will be directly integrated into the curriculum. In addition, the PIs will build on their past success in recruiting students from underrepresented groups in engineering to participate in the research. Research Experience for Teachers participants will be involved in the project and will create modules for high school science and pre-engineering courses to attract more students to these disciplines. Finally, to ensure that the results of this research are effectively communicated to industry, workshops will be conducted through the collaboration with industrial partners.

与福特汽车公司合作的学术联络与工业（GOALI）项目的资助机会提供资金，a）创建在连续弯曲下张力和B）通过创新的制造工艺利用这种行为的机制，提高金属成形性的基本理解。为了使行业利用连续弯曲-张力下实现可成形性的改善，需要基本现象的基础知识，预测材料行为的准确模型和创新的加工解决方案来利用这种效果。本研究将针对DP 780钢与AA 6022铝合金两种特殊材料进行研究。这两种材料都很受关注，并且越来越多地被评估用于各种重量敏感的应用，但是它们具有非常不同的微观结构，并且预计在张力下连续弯曲期间表现不同。主要研究人员和高级人员在实验力学、材料表征、基于微观结构和连续体的本构建模、过程模拟和金属板成形方面具有重要的相关专业知识，以确保本研究的成功。这项研究的结果将通过减少汽车等产品对环境的影响，设计，这将进一步降低组件的重量和成本。此外，研究生和本科生将受益于该项目的工业重点，其结果将直接融入课程。此外，PI将在过去成功招募工程学代表性不足群体的学生参与研究的基础上再接再厉。教师研究经验参与者将参与该项目，并将为高中科学和工程预科课程创建模块，以吸引更多的学生学习这些学科。最后，为了确保将研究结果有效地传达给工业界，将通过与工业伙伴的合作举办讲习班。
