The objectives of this Grant Opportunity for Academic Liaison with Industry (GOALI) research project are to a) create a fundamental understanding of the enhanced formability of metals during pulsed tube hydroforming, and b) develop analytical and numerical models of the process that will allow industries such as automotive and aerospace to capitalize on this behavior. Traditionally, loading during tube hydroforming is applied monotonically. Recently, it was demonstrated on actual components that if the loading is applied in a pulsed fashion (frequency ~1 Hz), significant gains in formability can be reaped. The mechanism(s) that lead to such improvements are presently unknown. The first objective of this research is to clarify these mechanisms by investigating different hypotheses experimentally. The materials to be examined are Advanced High Strength Steels and Aluminum alloys. The experimental findings will guide the research team into developing the analytical and numerical tools required by the industrial end-users to implement such technologies.This advanced hydroforming process and the models developed in this research will benefit society at large by reducing the environmental impact, and by enabling more aggressive product designs of products such as automobiles. Graduate and undergraduate students, including underrepresented groups in engineering, will benefit from the industrial focus of this project and from the integration of the results into the curriculum. The NSF Research Experience for Undergraduates (REU) and Research Experience for Teachers (RET) frameworks will be used to attract talented participants to aid with the research tasks. The RET participants will also identify high-school students to be engaged in research over the summer, thus attracting more students to STEM disciplines. Finally, the results of this research will be effectively communicated to industry through workshops conducted with the industrial partners (Alcoa, Ford, U.S. Steel).

该赠款与行业联络（Goali）研究项目的赠款机会的目标是a）对脉冲管中的金属增强性的基本理解，b）b）b）对流程的分析和数值模型进行分析和数值模型，从而允许诸如自动化和航空航天等行业以这种行为资本化这种行为。传统上，单调施加管道中的负载。最近，在实际组件上证明，如果以脉冲方式施加载荷（频率约1 Hz），则可以从可调性上获得显着提高。导致此类改进的机制目前未知。这项研究的第一个目的是通过实验研究不同的假设来阐明这些机制。要检查的材料是先进的高强度钢和铝合金。实验发现将指导研究团队开发工业最终用户实施此类技术所需的分析和数值工具。本研究的高级水理进程和本研究中开发的模型将通过降低环境影响，并促进更具积极性的产品设计，例如汽车型汽车（例如汽车）。研究生和本科生，包括工程中代表性不足的群体，将受益于该项目的工业重点以及结果将结果整合到课程中。 NSF研究经验（REU）（REU）和教师框架的研究经验将用于吸引才华横溢的参与者来协助研究任务。 RET参与者还将确定高中生在夏季从事研究，从而吸引更多的学生进入学科。最后，这项研究的结果将通过与工业合作伙伴（Alcoa，Ford，U.S. Steel）进行的研讨会有效地传达给行业。
