Discovery of Governing Laws in Real Multiphysics, Multicoupled Systems in Materials Processing

拟议的计划将桥梁基本概念与制造应用，也将桥梁学术HQP与工业同行。正如前几年所做的那样，HQP和这项工作的受益者将代表加拿大社会的不同组成部分。材料加工及其在制造业中的应用涉及各行各业的人，他们通过最终产品的共同点团结在一起。在焊接中，基本方面需要了解传热，流体流动，电磁学，等离子体，冶金学和固体力学（所有这些领域都是PI具有既定记录的领域）。参与此发现计划的HQP将掌握这些概念，并将其作为未来的员工，产品或通过知识转移带入行业。最接近申请的人是焊工和焊接技术人员，其中土著人、妇女和明显的少数民族所占比例很高。PI已经接待了焊工，焊接学生和其他感兴趣的社会成员，作为先前发现提案的一部分。在这些访问中，HQP学会了如何交流他们的学习和发现，项目的非学术成员了解了他们许多实际观察背后的“为什么”。也许最重要的是，障碍和偏见被同一目的的互补方法所取代;在这个例子中，焊接真实的部件。拟议计划的学术方面将进一步推动在以前的发现补助金中取得的重大理论和实验进展，这些补助金已出版并获得了着名的国际奖项。所开发的方法将直接帮助在定量水平上将工艺、结构和性能相互关联，重点是焊接，但也包括其他材料工艺，如铸造和金属加工（热或冷锻造、轧制等）。该计划中的活动将使用深刻的数学概念和对材料过程物理学的透彻理解，以产生可供行业从业者和其他研究人员使用的可靠指南和指南。该计划的教育目标是让未来的HQP接触现实生活中很难理想化的过程，并教他们提取这些过程的基本特征，以进行定量预测。除了通过同行评审的出版物和课堂进行传统的知识传播之外，目前还将继续努力，通过上传视频和原始数据以及社交媒体，利用互联网传播知识。所采用的方法是数学建模和实验测量的组合，从基本原理产生一般的设计规则。PI已经拥有所有必要的软件、实验设施和理论基础，以开发和实践所提出的方法。

The proposed program will bridge fundamental concepts with manufacturing applications and will also bridge academic HQP with industrial counterparts. As done in previous years, the HQP and beneficiaries from this work will represent the diverse composition of Canadian society. Materials processing, and its application to manufacturing involves people from all walks of life, united by the common thread of a final product. In welding, the fundamental aspects require understanding of heat transfer, fluid flow, electromagnetics, plasmas, metallurgy, and solid mechanics (all are areas in which the PI has an established track record). The HQP involved in this discovery program will master these concepts, and bring them to industry as future employees, as products, or through knowledge transfer. The people closest to the applications are the welders and welding technologists, with a high proportion of indigenous, women, and visible minorities. The PI has hosted welders, welding students, and other interested members of society as part of the previous discovery proposal. During these visits, the HQP learned how to communicate their learning and findings, and the non-academic members of the project learned the “why” behind many of their practical observations. Perhaps most importantly, barriers and prejudices were replaced by appreciation of complimentary approaches to the same end; in this example, welding of real components.***The academic aspect of the proposed program will further the significant theoretical and experimental progress made in the previous Discovery grant, which have been published and received prestigious international awards. The methodologies developed will be of direct help in relating processing, structure, and properties to each other at a quantitative level, with an emphasis on welding, but also including other materials processes such as casting, and metalworking (hot or cold forging, rolling, etc.). Activities in this program will use deep mathematical concepts and a thorough understanding of physics of materials processes to produce reliable guidelines and heuristics that can be used by practitioners in industry and by other researchers. The education objective of this program is to expose future HQP to real-life processes that are very difficult to idealize, and to teach them to distill the essential features of these processes to make quantitative predictions. Beyond the traditional transmission of knowledge through peer-reviewed publications and the classroom, current efforts will be maintained to disseminate learning using the internet by uploading videos and raw data, and social media.***The methodologies to be employed are a combination of mathematical modeling and experimental measurements to generate general design rules from fundamental principles. The PI already counts with all necessary software, experimental facilities, and theoretical foundation to develop and bring to practice the methodologies proposed.**
