Sustainable manufacturing or green manufacturing aims to reduce environmental impact and reduce waste. Thus, the performance of manufactured parts becomes a game changer through characterizing not only the functional properties such as strength-to-weight ratio, specific stiffness and toughness but also end-of-life, re-use and recycle properties. Transcription of these properties into manufactured parts requires the integration of the micro-meso-macro scale interactions in manufacturing processes. Conventionally in manufacturing processes, the relationship structure-properties and the relationship properties-performance are considered decoupled. Consequently, the simultaneous interactions between all three characteristics structure, properties and performance remain unknown. I will present a new approach that accounts for the structure-properties-performance relationship as a reciprocal function in designing and manufacturing the product performance. Reciprocity is based on first principles and physics-based models of understanding and controlling the mechanisms of generating the performance in manufactured parts. Mechanism such as bonding, strengthening, CO₂ absorbing and decaying are simulated through multi-scale modeling and machine learning and further used in predicting the performance of parts. I will provide examples of applying this approach in enhancing performance of joining dissimilar materials and forming stronger green composites.

Dr. Banu is a research associate professor in the Department of Mechanical Engineering at the University of Michigan, Ann Arbor. She earned her PhD in mechanical engineering from University of Galati, Romania and RIKEN Institute, Japan in 2000. Since joining the University of Michigan in 2013, she developed a new research program in green and sustainable manufacturing to advance the use of eco-friendly lightweight materials in future transportation in order to address the global challenge of reducing CO₂ emissions. Findings from the multi-scale modeling developments of metals and polymer composites in her research program have demonstrated also that coupling effects from micro-, meso- and macroscale enable achieving smart attributes of conventional manufacturing processes. In addition, she is a core contributor and former technology portfolio manager of the American Lightweight Material Manufacturing Innovation Institute - LIFT, the flagship-manufacturing institute in the U.S. She is the recipient of the 2019 University of Michigan Research Faculty Achievement Award, and the 2017 Kenneth M. Reese Outstanding Research Scientist Award of the College of Engineering at the University of Michigan. She is an Associate Editor of the Journal of Manufacturing Processes and member of the Editorial Board of Advances in Industrial and Manufacturing Engineering Journal.
