AME Seminar Series welcomes Dr. Surya R. Kalidindi for the first seminar of the new year. Kalidindi is a Professor at the School of Computational Science and Engineering as well as the School of Materials Science and Engineering at the Georgia Institute of Technology.
Kalidindi will begin his seminar presentation at 10:30am in the Hitachi Conference Room located in 214 Felgar Hall. His presentation is titled, “Data Science Approaches for Mining Structure-Property-Processing Linkages from Large Datasets.”
Abstract: Materials with enhanced performance characteristics have served as critical enablers for the successful development of advanced technologies throughout human history and have contributed immensely to the prosperity and well-being of various nations. Although the core connections between the material’s internal structure, its evolution through various manufacturing processes and its macroscale properties in service are widely acknowledged to exist, establishing this fundamental knowledge base has proven effort-intensive, slow and very expensive for a number of candidate material systems being explored for advanced technology applications. It is anticipated that the multi-functional performance characteristics of a material are likely to be controlled by a relatively small number of salient features in its microstructure. However, cost-effective validated protocols do not yet exist for fast identification of these salient features and establishment of the desired core knowledge needed for the accelerated design, manufacture and deployment of new materials in advanced technologies. The main impediment arises from lack of a broadly accepted framework for a rigorous quantification of the material’s internal structure and objective identification of the salient features in the microstructure that control the properties of interest. Materials Informatics focuses on the development of data science algorithms and computationally efficient protocols capable of mining the essential linkages in large multiscale materials datasets (both experimental and modeling) and building robust knowledge systems that can be readily accessed, searched and shared by the broader community. Given the nature of the challenges faced in the design and manufacture of new advanced materials, this new emerging interdisciplinary field is ideally positioned to produce a major transformation in the current practices. The novel data science tools produced by this emerging field promise to significantly accelerate the design and development of new advanced materials through their increased efficacy in gleaning and blending the disparate knowledge and insights hidden in “big data” gathered from multiple sources. Our ongoing research has outlined a specific strategy for data science enabled development of new/improved materials and key components of the proposed overall framework are illustrated with examples.

A MESSAGE FROM THE DIRECTOR:
Greetings from the OU School of Aerospace and Mechanical Engineering. It’s been a busy year with exciting developments in research, renovation, student success and faculty accomplishments. I would now like to share with you our annual e-newsletter for 2014.
Happy Holidays from all of us at AME!

The students of the course User-Centered Design along with their professors Dr. Diana Bairaktarova and Dr. Zahed Siddique explored design-thinking, innovation, creativity, prototyping, empathic and verification design throughout the semester. The focus of the course was learning and experiencing design as a space rather than a step by step process with a toy prototype as a course project.
The students individually applied their knowledge from the course on a toy design project. They created blueprints for the design, a prototype of the toy and an informational poster about the toy. Students hosted a Toy Fair for others to view their toys and meet the designers. The toys along with their posters and the designers’ biographies are now on display for the months of December and January in the main lobby of the Bizzell Library.

Recently the Mechanical Engineering Capstone students were given a task. The task was to design, build and test a SHARK system capable of moving over land a distance of eight feet, and then enter a harbor. The SHARK must cover the eight feet as rapidly as possible. Upon entering the ‘harbor’ the SHARK must retrieve as much Klepp as possible within set time limits.
The design and construction of the SHARK were subject to the restrictions and conditions.
- The design must start and operate with one switch
- The design must be completely autonomous
- The design must be self-contained
- The total system weight (dry) should not exceed 5lbs
- The system at rest should fit in an imaginary cube
The performance of SHARK was tested in two areas:
- Land speed – this event measured the speed of the SHARK over a distance of eight feet. The course began at a start line eight feet away from the ‘harbor’ and finished in the ‘harbor.’ Timing began when the foremost part of the SHARK crossed the start line and ended when the SHARK entered the pool.
- Retrieval rate – this was a measure of how much Klepp the SHARK could retrieve. Upon entering the water, the SHARK had two minutes to retrieve as much Klepp as possible. In the test, Klepp was represented by Styrofoam packing ‘peanuts.’ The number of peanuts collected or retrieved by the SHARK in two minutes was counted and expressed as a rate: Klepp retrieval per minute.
Each group was allowed to put their SHARK through the test twice. Groups were allowed two minutes to set up for a test and one minute to remove their device from the testing area.
Scoring was completed for points of land speed and points for retrieval rate. The total points for a test was the sum of the land speed and retrieval rate minus deductions due to penalties, i.e. The final score for a group was the highest from the two tests. Lastly, the group with the most points was announced as winners of the competition. The winning team consisted of Jacob Pickle, Scott Maxwell, Brooke Hitt, Lars Glasemann, and Jackson Autrey. Congratulations!
The winning team with their SHARK.
The team overlooks the judge as he counts the ‘Klepp.’
On Tuesday, November 25, 2014, Dr. Tahira Reid visited AME for a seminar presentation. Her seminar presentation was titled, “The Influence of Social and Cultural Considerations on Engineering and Design.”
Abstract: In this talk, Dr. Reid will discuss two projects to illustrate how social and cultural considerations influence design methods. In the Beauty of Mechanical Engineering project, Dr. Reid and her students are conducting experiments to understand how heat moves through curly hair and the mechanisms that cause permanent structural changes in the hair (i.e., heat damage). Currently, trained professionals in the hair industry cannot predict when heat damage will occur and often rely on heuristics and intuition in their hair care approaches. In addition, scientists that have conducted studies with heat and hair have often used Caucasian hair which cannot be generalized to all ethnic groups; they have also conducted experiments that are not ecologically consistent with individuals’ use context. As a result, a number of lay scientists have emerged whose use of contexts are ecologically valid, but are lacking the experimental and quantitative rigor that engineers can provide. With hair care being a multi-billion dollar industry and having meaning for a vast majority of the population, research of this kind is important. In the Socially Conscious Design project, Dr. Reid and her students are exploring ways that compassion can help with problem framing and enhancing design solutions. There are some product interactions, namely in medical environments, in which the design of a product/system elicits fear and anxiety within individuals. The ultimate goal of this research is to use interdisciplinary methods to examine ways in which these emotional needs can be considered during the design process.
Bio: Dr. Tahira N. Reid is an Assistant Professor in the School of Mechanical Engineering at Purdue University and is the director of the Research in Engineering and Interdisciplinary Design (REID) Laboratory. Her research interests include developing methods that help engineers think critically about non-technical issues and their impact on engineered design solutions. Prior to arriving at Purdue in 2011, she completed a postdoctoral fellowship in the Mechanical Engineering department at Iowa State working in the Interdisciplinary Research in Sustainable (IRIS) Design Laboratory under the mentorship of Erin MacDonald. In 2010, she received her Ph.D. from the University of Michigan in Design Science, with Mechanical Engineering and Psychology as her focus areas. Dr. Reid received both her B.S. and M.S. degrees in Mechanical Engineering from Rensselaer Polytechnic Institute in 2000 and 2004, respectively. She received national attention for patenting a childhood invention: a Double Dutch jump rope device. In 2000, she exhibited her device at the Smithsonian during the Playful Mind’s exhibit and demonstrated it on NBC’s Today Show. Her story has been featured in numerous news media sources and is featured in two children’s books.
On October 25, 2014 students of OU’s American Institute of Aeronautics and Astronautics (AIAA) attended the Society of Flight Test Engineer’s Symposium at the Worthington Hotel in Fort Worth, Dallas. The symposium was attended by companies like Bell Helicopter, Lockheed Martin, Bombardier and Scaled Composites. The event was directed by the high level test engineering field engineers and was an eye-opening experience for the students.
“This was the greatest opportunity of my college career to meet and socialize with industry professionals.”- Josiah Lund, President AIAA
In addition to the symposium, the students also had the opportunity to visit the Lockheed Martin to see the F35 Assembly Line and Simulators. Several students also went to Love Field to visit the Maintenance and Engineering Department of Southwest Airlines. These events are very important to both inspire the students and also create valuable relationships with potential mentors in the industry.
“I really like that our sophomores were able to visit a company. The F35 line was exhilarating!” – Bipin Varghese, PR AIAA
On Wednesday, November 12, 2014, Dr. Jandro Abot visited AME for a seminar presentation. His seminar presentation was titled, “Self-Sensing Composite Materials Using Carbon Nanotube Yarns: A New Paradigm in Structural Health Monitoring.”
Abstract: Composite materials are widely used in aerospace structures and many applications because of their superior specific stiffness and strength respect to weight. However, monitoring their structural health still remains too complex and difficult to implement in an integrated and distributed manner. This presentation is about integrated structural health monitoring in polymeric and composite materials using carbon nanotube yarns. Carbon nanotubes are grown into arrays that can be drawn into webs and further twisted into yarns that contain thousands of carbon nanotubes in their cross-sections. These carbon nanotube yarns are lightweight, stiff, strong, ductile and electrically conductive fiber-like materials that we are studying as piezoimpedance-based sensors. The proven concept of real-time, integrated, and widely distributed damage detection and strain measurement using carbon nanotube yarn sensors is presented including the latest experimental results. The coupled mechanical, electrical and thermal response of the carbon nanotube yarns is of significant importance for their use as sensors and recently obtained results are presented including a not-before observed negative piezoresistance response. The effect of composition and structure of the carbon nanotube yarns on that coupled response is also discussed. The present challenges and proposed approaches for robust real-time structural health monitoring that eventually leads to condition-based maintenance are outlined for aerospace structures and other components, devices, and structures.
Dr. Jandro Abot is an Associate Professor in the Department of Mechanical Engineering, Director of the Intelligent Materials Laboratory, and Director of International Engineering Program Development of the School of Engineering at The Catholic University of America. He was previously an Assistant Professor in the Department of Aerospace Engineering and Engineering Mechanics at the University of Cincinnati. Prior to that, he was a Postdoctoral Fellow at Northwestern University where he had received his Ph.D. and M.S. degrees in Theoretical and Applied Mechanics. Dr. Abot also holds a 6-year degree in Structural Engineering from the Universidad de la República in Montevideo, Uruguay. Dr. Abot’s expertise is on the science and technology of composite materials and structural health monitoring of structures using carbon nanotube-based sensors. Dr. Abot authored or co-authored one hundred journal and proceeding papers and led research projects sponsored by AFOSR, NASA, and Fulbright and collaborated on projects sponsored by NSF, ONR, and industrial consortiums. Dr. Abot taught nineteen different engineering courses in Solid Mechanics, Materials Engineering, Experimental Mechanics and Introduction to Mechanical and Aerospace Engineering, always receiving very good students’ evaluations. Dr. Abot is always committed to advising many graduate students and mentoring undergraduate students in the framework of research projects, and actively engaged in many departmental and school service activities such as recruitment, accreditation and international programs.

The School of Aerospace and Mechanical Engineering Graduate Student Community (GSC) hosted their first research poster fair on Tuesday, November 4, 2014 at Devon Energy Hall. The student participants were all AME graduate students ranging from first-year graduate students to those nearing Ph.D. completion. The fair hosted over 15 participants who presented their research ranging from theoretical modeling research to experiment-based research. Three judges evaluated each participant’s poster and information along with a five minute explanation of the research from the participant. The judges were Dr. Yingtao Liu, AME Assistant Professor; David Campbell, Engineer at Tinker Air Force Base; and Beth Murray, Career Manager of Engineering Workforce Development at Tinker Air Force Base.
The hope of the poster fair was to provide students with presentation experience as well as respond to the judges challenging questions and critiques.
“Anybody can get up and do a slide show presentation, but when you have someone who actually knows [what] you’re talking about, they’re going to ask you critical questions,” Stewart Ohler, Ph.D. candidate, said.
The GSC awarded the top four winners with a cash prize and a certificate. The winners were as follows:
1st Place: Arun Balakrishnan (Ph.D. Candidate, Aerospace Engineering)
2nd Place: Lucas Balmer (Master’s Degree Student, Mechanical Engineering)
2nd Place: N. Anand Balu (Master’s Student, Mechanical Engineering)
2nd Place: Maryam Sabeghi and Jelena Milisavljevic (Master’s Students, Mechanical Engineering).
Congratulations to the winners and congratulations to the GSC for a successful event!
