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联络的学术联络机构的赠款机会为a）提供资金，a）对这种机制建立基本理解，从而增强金属在连续弯曲期间和b）利用这种行为的基础。通过创新的制造过程。为了使该行业利用持续的弯曲弯曲以实现可表现性，对基本现象的基本知识，准确的模型来预测材料行为和创新的处理解决方案以利用此效果。这项研究将研究两种特定材料，即DP780钢和AA6022铝合金。这两者都是有趣的，并且对各种体重敏感的应用进行了越来越多的评估，但是具有非常不同的微观结构，并且期望在连续弯曲下弯曲期间的行为不同。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性的组成型建模，过程模拟和钣金形成方面具有重要的相关专业知识，以确保这项研究的成功。通过减少汽车等产品的环境影响并实现更具侵略性的产品设计，这将使社会受益匪浅，这将进一步降低组件的重量和成本。此外，研究生和本科生将从该项目的工业重点中受益，结果将直接纳入课程。此外，PI将基于他们过去的成功来招募工程中代表性不足的小组的学生参加研究。教师参与者的研究经验将参与该项目，并将为高中科学和工程学课程创建模块，以吸引更多的学生进入这些学科。最后，为了确保这项研究的结果有效地传达给行业，将通过与工业合作伙伴的合作进行讲习班。
