Kuang-Hua Chang, AME and David Ross Boyd Professor, recently finished and published his fourth book in a four-book series. Chang was approached by Academic Press, a leading publisher of scientific books, in 2005 to write a textbook focused on computer aided engineering design. He began writing The Computer Aided Engineering Design Series in 2009 while on sabbatical leave, publishing two books in 2013 followed by the final two in 2014.
“I have been interested in writing such a book for a long time,” said Chang. “These books are very unique as many engineering design books discuss conventional design principles. This series focuses on modern e-Design paradigm, computer design tools, current technology and different perspectives.”
The textbooks target mechanical, aerospace and industrial engineers studying design as well as engineers interested in learning computer design tools such as Pro/ENGINEER® and SolidWorks® in the context of the e-Design paradigm. Chang also uses his textbooks to teach four courses at AME as electives for seniors and graduate students. These courses include Intro to CAD, Concurrent Design and Manufacturing, Computer-Integrated Manufacturing and Design Theory and Methods.
For more information on each textbook, please click the corresponding title:
- Book One: Product Design Modeling
- Book Two: Product Performance Evaluation
- Book Three: Product Manufacturing and Cost Estimating
- Book Four: Design Theory and Methods
“These books benefit the students while learning design,” said Chang. “It sets them up to learn the methods and tools used in the industry while allowing the students to be competitive in the field.”
Next on Chang’s to do list is combining all four books ranging from 418 pages to 549 pages into one single book, e-Design: Computer-Aided Engineering Design, to be published by Academic Press in 2015.
AME Assistant Professor Yingtao Liu received a $15,000 research grant from the OU Research Council Faculty Investment Program to develop novel polymers with self-healing capability. Once complete, this exploratory project will be a solid foundation for the design, fabrication and development of multifunctional polymers and composites for aerospace, mechanical and civil engineering applications.
“We will focus on the synthesis and characterization of self-healing polymers in this project,” said Liu. “The self-healing process of the proposed polymers will mimic the biological systems that can autonomously repair the physical damage and recover the load ability after damage.”
Liu’s long term career goal is to develop an adaptive structural health management system for multi-physics damage diagnosis and prognosis by combining multifunctional materials, intelligent and multi-scale sensing, nondestructive evaluation, multi-scale and probabilistic modeling into a general framework. The successful development of intelligent materials and structural systems will be a game changing improvement of damage diagnosis, structural maintenance and risk management for various engineering applications. This project, which focuses on the self-healing capability, is one of the key elements in Liu’s long term research plan.
A MESSAGE FROM THE DIRECTOR:
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
- 1 ft. X 1 ft. X 1 ft.
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!
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.

The School of Aerospace and Mechanical Engineering Board of Advisors attended their annual fall meeting on Friday, November 7, 2014. The BOA had a busy day with a full agenda. They held their meeting in the Hitachi Conference Room in Felgar Hall. In addition, the Chesapeake Scholars were invited to the luncheon with the BOA and received their Chesapeake Scholars certificate from BOA Chair and Chesapeake Vice-President, Dave Bert. The Chesapeake Scholars are Morgan Andersen, David Doshier, Cameron Riney and Timothy Willis.
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!
