NIMSI SEMINAR with  Rebecca Cai

NIMSI SEMINAR

June 8, 2021 @ 1pm CDT Online Seminar via ZOOM

ABSTRACT

The increasing complexity and severity of service conditions in areas such as aerospace and marine industries, nuclear systems, microelectronics, batteries, and biomedical devices etc., imposes great challenges on the reliable performance of metal subjected to simultaneous surface stress and corrosion. However, the design of strong and corrosion-resistant alloys, especially those containing lightweight elements such as Al are challenged by the tradeoff between strength and corrosion resistance. Solute tends to have a small equilibrium solubility limit in Al due to the relatively large negative enthalpy of mixing with Al. As a result, the formed precipitates strengthen the alloys, but compromises corrosion resistance due to their micro-galvanic coupling with the metal matrix. Towards this end, this talk will focus on the development of novel microstructure design strategies for metals to mitigate the combined attack of wear and corrosion (i.e. tribocorrosion) under harsh conditions. Two design strategies will be discussed to overcome this long-standing dilemma: by forming solid solution alloys and nanostructured multilayers. These studies provide insights for general design guidelines to engineer more robust, high-performance metals for use under harsh conditions.

Manufacturing Seminar: Yung C. Shin

MANUFACTURING SEMINAR

May 7, 2021 @ 3pm EST Online Seminar via ZOOM

ABSTRACT
Additive manufacturing (AM) provides unprecedented capabilities of building parts with complex geometry and customized properties. Additive manufacturing offers potential forgoing far beyond building complex parts. Despite the explosively growing interest and promising prospective, there remain many grand challenges to overcome to make metal AM widely acceptable in industry. This talk will first highlight various novel applications of AM that have been developed over the last twenty years in my group, spanning from novel material synthesis, functionally gradient materials, remanufacturing and nanoscale AM. Secondly, I will describe the ongoing efforts for developing key enabling technologies that can help expedite the implementation of AM via modeling of processes, microstructure, and resultant properties as well as in process monitoring schemes. Finally, some future challenges and opportunities to be addressed will be described.

Manufacturing Seminar: Ping Guo

MANUFACTURING SEMINAR

April 23, 2021 @ 3pm EST Online Seminar via ZOOM

ABSTRACT
Historically, advancement in manufacturing technology has frequently led to scientific breakthroughs, revolutionary product design, and creation of new consumer markets. These technological improvements can be categorized into two groups: incremental upgrades of the traditional approaches, and disruptive innovation involving outside-the-box thinking. In this talk, Prof. Guo will present research efforts utilizing non-traditional physical principles. Particularly, two examples will be presented to demonstrate outside-the-box thinking in innovation. The first example introduces a vibration-assisted machining method to create wavelength-scale gratings for structural coloration and advanced optics. In the second example, he will introduce new non-contact actuator designs purely based on structural vibration. Finally, he will discuss some new research ideas and hopefully offer inspiration for innovation in future manufacturing.
Dr. Ping Guo is an Assistant Professor at the Department of Mechanical Engineering, Northwestern University. He received his B.S. degree in Automotive Engineering from Tsinghua University in 2009 and his Ph.D. degree in Mechanical Engineering from Northwestern University in 2014. Before joining Northwestern University in September 2018, he spent four years at the Chinese University of Hong Kong as an Assistant Professor.

Dr. Guo’s research interests center on the paradigm of micro/meso-scale manufacturing, including surface texturing, process micro-mechanics, miniature machine tools, micro-additive manufacturing, etc. He is the recipient of the Outstanding Young Manufacturing Engineer Award from SME 2020, the Young Investigator Award from the International Symposium on Flexible Automation 2018, and the Hong Kong Research Grants Council Early Career Award 2016.

Manufacturing Seminar: Cooper

MANUFACTURING SEMINAR

April 9, 2021 @ 3pm EST Online Seminar via ZOOM

ABSTRACT
Industry already accounts for approximately one-third of global emissions and these emissions are growing quickly as the developing world industrializes. We need sustainable materials processing and Re-X (e.g., recycling) solutions that fit the scale of the challenge and can be deployed in the short as well as long term. This talk first highlights the sources of industry emissions now and in the future, and then the opportunity to reduce emissions by increasing material efficiency in all stages of the product life cycle. We present a fast and easily updateable method for calculating material flows and identifying material efficiency opportunities. We then demonstrate the potential for material efficiency across the life cycle; e.g., manufacturing process innovations for reduction and reuse of light metal scrap, and increased end-of-life metal recycling in the face of increased scrap contamination and changing demand. Finally, we explore some of the most critical basic and applied research directions that can address industrial emissions at a relevant scale.

Dan Cooper is an Assistant Professor in the Mechanical Engineering department at the University of Michigan. He heads the Resourceful Manufacturing and Design (ReMaDe) group, which is dedicated to pursuing environmental sustainability through process innovations in resource efficiency and optimized manufacturing and recycling supply chains. Dan’s work is at the nexus between Industrial Ecology (IE) and Mechanical Engineering (ME): he uses IE methodologies such as material flow analyses and life cycle assessment to identify opportunities and quantify impacts at the process, factory, and supply chain scale, and then pursues an experimental and mechanistic modeling approach to generate the scientific knowledge underlying those opportunities. Dan received all his degrees in Mechanical Engineering from the University of Cambridge before completing a post-doc at MIT. He is the recipient of the 2020 ASME Ben C. Sparks Education Medal, and the 2020 SME Outstanding Young Manufacturing Engineer Award.

Manufacturing Seminar: Tawfick

MANUFACTURING SEMINAR

March 26, 2021 @ 3pm EST Online Seminar via ZOOM

The future of work is shaped by the synergy between ubiquitous automation and artificial intelligence. Automation is currently driven by electric motors, which deliver clean mechanical actuation and are even already replacing engines in transportation, in addition to their role in robotics, prosthetics and energy. In this talk, I will describe a roadmap to replace bulky electric motors and exploit instead bioinspired materials, processes and self-organization phenomena for automation.

First, I will describe the use of liquid surface energy to manufacture surface textures by self-organization, as well as to actuate morphing surfaces. Next, I will describe the design and production of artificial muscles which use electric, thermal, or chemical energy to generate contractile motion.
These examples shed light on the future of work propelled by new materials, nonlinear mechanics and unusual manufacturing processes.
Sam Tawfick is an Associate Professor of Mechanical Science and Engineering and at the Beckman Institute at the University of Illinois.
