Non-technical Abstract:The project will fund 10-week long research experiences of three groups of up to five undergraduate and graduate students from The Ohio State University (OSU) at the Institute of Forming Technology and Lightweight Construction (Institut fuer Umformtechnik und Leichtbau, IUL), in the Technical University at Dortmund (TU Dortmund) during the summer months of 2017 to 2019. The students will work on research topics related to ongoing collaborations between faculty members at TU Dortmund and OSU. The research conducted will form part of undergraduate research experiences, or graduate theses, of the participating students. The project takes advantage of complementary institutional research strengths: fundamental physical modelling and understanding of the materials, processes, and systems involved in forming (a strength of OSU), and validation of forming process ideas by application in laboratory and industrial scales (a strength of IUL). As a result of these research experiences, OSU students will develop a nuanced appreciation of research approaches and perspectives in the theme area, and will be better able to incorporate such insights into their own research efforts. Involvement in ongoing research at IUL will also introduce students to the state of the art in advanced manufacturing, and provide them insights into topics of current industrial interest in Europe. Intensive German language instruction prior to the visit to Germany will enable more effective student experiences.Technical Abstract:The unifying project theme is the forming and manufacture of lightweight high-performance components, with individual research efforts focusing on one or more of the following aspects: materials modeling and characterization, forming process innovation, and product and process design and performance enhancement. More specifically, the research topics investigated will include investigations into the underlying physics of the vaporizing wire effect in impulse metal forming and development of more energy efficient vaporizing foil welding; improved material behavior modeling of thermomechanical processing; experimental characterization, prototyping, and numerical modeling of forming of parts with metals, composites, and hybrid materials; use of X-ray and neutron imaging techniques to characterize local defects or voids resulting from metal forming; and use of physics-based process models to achieve improved process and product property control in the manufacture of optimized lightweight structures. The project will also establish the foundation for a broader and longer-term educational and research partnership between OSU and TU Dortmund.

非技术摘要：该项目将资助三组最多五名本科生和研究生的为期10周的研究经验，他们来自俄亥俄州州立大学（OSU）的成型技术和轻质结构研究所（Institut fuer Umformtechnik und Leichtbau，IUL），在多特蒙德技术大学（TU多特蒙德），在2017年至2019年的夏季。学生将从事与多特蒙德理工大学和俄勒冈州立大学教师之间正在进行的合作有关的研究课题。所进行的研究将构成参与学生的本科研究经验或研究生论文的一部分。该项目利用了互补的机构研究优势：基本物理建模和对材料，工艺和成型系统的理解（OSU的优势），以及通过实验室和工业规模的应用验证成型工艺理念（IUL的优势）。由于这些研究经验的结果，俄勒冈州立大学的学生将开发在主题领域的研究方法和观点的细微差别的赞赏，并将能够更好地将这些见解纳入自己的研究工作。参与IUL正在进行的研究还将向学生介绍先进制造的最新技术，并为他们提供对欧洲当前工业兴趣主题的见解。在访问德国之前进行密集的德语教学将使学生获得更有效的体验。技术摘要：统一的项目主题是轻质高性能部件的成型和制造，个人研究工作集中在以下一个或多个方面：材料建模和表征，成型工艺创新，产品和工艺设计和性能增强。更具体地说，调查的研究课题将包括在脉冲金属成形和更节能的汽化箔焊接的发展汽化线效应的基础物理的调查;改进的材料性能建模的热机械加工;实验表征，原型，和金属，复合材料和混合材料的零件形成的数值模拟;使用X射线和中子成像技术来表征由金属成形产生的局部缺陷或空隙;以及使用基于物理的工艺模型来实现在优化的轻质结构的制造中改进的工艺和产品性能控制。该项目还将为俄勒冈州立大学和多特蒙德理工大学之间更广泛和更长期的教育和研究伙伴关系奠定基础。
