Professional Highlights

1. One of the major contributions of Prof. Sehitoglu is that he produced PhD students who became faculty members and have taught failure of materials to a generation of students at their respective institutions. His former PhD students in academia include R. Neu (Georgia Institute of Technology), K. Gall (Georgia Institute of Technology), I. Karaman (Texas A&M University), Y. Jiang (University of Nevada, Reno), E. Alaca (Koc University, Istanbul, Turkey), D. Canadinc (Koc University, Istanbul, Turkey), R. Hamilton (Penn State University) and M. Sangid (Purdue University). Currently, he is supervising 6 graduate students, 1 post-doc and 1 international visitor. In addition, he has provided mentorship to young faculty, particularly to Professors Tom Mackin and Taher Saif in his own department. Professor Sehitoglu served as Interim Head of Mechanical Science and Engineering Department during 2004-2005 and was selected as Head of the Department in July 2005. The Department name change to ‘Mechanical Science and Engineering’ and merger with Theoretical Applied Mechanics Department became effective August 2006. He was instrumental in recruiting over seventeen new faculty in emerging areas of cellular biomechanics, nano-mechanics, dynamics, and fluids over the last five years. The new hires invigorated the MechSE programs with new perspectives and areas of expertise. Professor Sehitoglu, building upon the longstanding strengths of programs in mechanical engineering and in mechanics, led the new MechSE (Mechanical Science and Engineering) Department at Illinois to a bold, new approach to research. He has created an environment that is conducive to integrating biology, chemistry, applied mathematics and applied physics with mechanical engineering and engineering mechanics disciplines. The result has been leading-edge research that serves some of society’s greatest needs, in the areas of energy; disease detection; for cost-effective and non-polluting modes of transportation; for manufacturing solutions that will facilitate the transition of nanoscale discoveries from the laboratory to the public and more. Overall, the result has been to position the department for leadership in a rapidly changing world. He has also influenced the practicing materials and mechanical engineers as Director of the University of Illinois Fracture Control Program (http://fcp.mechse.illinois.edu/), a consortium of ground vehicle companies with a research emphasis on the

25

fatigue of metals. He has been the lead instructor at nearly 40 well-attended basic and advanced short courses on fatigue and fracture that draw participants from industrial and academic settings around the world. In each of these courses the attendance ranged from 60 to 100 participants. Professor Sehitoglu served as Editor-in-Chief of the ASME Journal of Engineering Materials and Technology. He is also on the editorial board of Journal of Engineering Fracture Mechanics and the International Journal of Fatigue, and has served in the Scientific Organization Committee of numerous international meetings. From 1991-1993, he was the director of the Mechanics and Materials program within the National Science Foundation, where he played a key role in foundation-wide initiatives in materials synthesis and processing and advanced materials, and in the establishment of the Institute for Mechanics and Materials, an NSF funded Institute. He served as co-chairman of the 2003 Low-Cycle Fatigue and Elastoplastic Behavior of Materials Conference, the Shape Memory Conference in Istanbul, Turkey in 2009 and several Thermo-mechanical Fatigue of Materials symposia. He also serves the profession as a reviewer for several leading journals and a variety of federal granting agencies.

2. Professor Sehitoglu is known for his work in mechanics of materials, has studied several areas of importance, such as mechanics of fatigue and materials science of deformation, and was also instrumental in launching several new initiatives in his department as Department Head. The underlying philosophy in his studies has been to emphasize a stronger connection between continuum approaches and physical mechanisms of failure in engineering materials and structures. For example, he has focused attention on transforming materials with a combination of most advanced tools at different length scales. These tools include single crystal experiments with extensive digital image correlation on one hand and the use of electronic structure calculations of energies for twinning and phase transformation on the other. It would be most fitting to make a presentation of the advanced (experiments and simulation) tools that will highlight the intellectual vigor in mechanical engineering and mechanical science. Professor Sehitoglu is uniquely qualified to make such a presentation because he has made contributions on both the experimental and modeling fronts. Professor Sehitoglu is the author of more than 250 journal articles in the areas of thermo-mechanical fatigue, thermo-elastic phase transformations, and modeling of plasticity in metals. From his work dating to the mid-1980s on fatigue at high temperatures, Professor Huseyin Sehitoglu has made many important scientific contributions in the area of shape memory and thermo-mechanical fatigue, and contributed to the advancement of knowledge in fatigue of metals in general, and specifically the understanding of twinning and slip in metals through materials science and mechanics studies.

3. Profesor Sehitoglu made several significant contributions to life prediction of high temperature components studying steels and nickel based superalloys in the 1980 and 1990s. He continued to work in the 1990s on Al alloys, and more recently (2005-) developed an important model for fatigue crack initiation in nickel based superalloys. The field of thermo-mechanical fatigue involves the response of materials under cyclic mechanical and thermal loads where the deformation and damage mechanisms can be synergistically coupled. Because of the complexity required in experiments and modeling and the coupled mechanisms few researchers made sustained contributions in this field. He developed a reliable method for predicting life that successfully interpreted and synthesized experimental work on creep, plasticity and high temperature corrosion. These works were published in a two part paper published in Materials and Metallurgical Transactions with his graduate student Richard Neu (currently Professor at Georgia Tech.). These papers are entitled “Thermo-mechanical fatigue, Oxidation, Creep, Part I: Experiments & Part II: Life Predictions”. By systematically conducting experiments in helium and air atmospheres , in-phase versus out-of-phase loading he was able to express the contribution of oxidation damage and creep damage to reduction in fatigue lives. The primary damage mechanisms under oxidation, creep, and fatigue were incorporated into a comprehensive life model in a series of papers. His research developed stress-strain relations that incorporated the changes in microstructure of the material. Previous treatments separated creep and plasticity components of strain, he devised experiments to establish the flow rule and hardening and recovery terms in unified constitutive equations. During the late 1980s and early 1990s he served as the chairman of the Research and Education subcommittee within ASTM (American Society of Testing Materials) that focused on thermo-mechanical fatigue and new advances in fatigue, he was Associate Editor of J. Pressure Vessel and Piping. He was a keynote speaker in a NASA (1986) Workshop on Thermo-mechanical fatigue and in NATO Advanced Study Conferences (1995) in this area, edited two books and authored a chapter in the ASM Handbook, Vol.19, on the topic of Thermo-mechanical Fatigue (1996). This chapter is the definitive piece of work on thermo-mechanical fatigue. He was the symposium chairman for the ASTM Conference on Thermo-mechanical Fatigue in 1991 and co-chair in 1998. He was asked to be the closing speaker at the European Joint Research Center Conference on Thermo-

26

mechanical Fatigue held in Petten, Holland in 1995 and in 2001 in Paris, France. In 2003, he was the US chairman of the Low Cycle Fatigue and Elastoplastic Behavior of Materials held in Berlin, Germany and was a member of the Scientific Committee for CAMPS in 2002. The experimental techniques he developed are now adapted within ASTM Thermo-mechanical Fatigue testing standards. He clarified the procedures for out-of-phase and in-phase thermo-mechanical loading and experiments to simulate constraint that was developed originally in his PhD thesis in 1983 under the direction of late Professor JoDean Morrow. The model for thermo-mechanical fatigue Professor Sehitoglu developed is utilized in the internal software for life calculations in Ford Motor Co. for analyzing thermo-mechanical fatigue of pistons and cylinder heads. His thermo-mechanical fatigue experimental techniques were utilized by Ford in their internal work and they have written a finite element code based on the stress-strain/life model developed in Professor Sehitoglu’s work. His models have been utilized by commercial software firms, such as nCode (http://www.ncode.com/) to develop a thermo-mechanical fatigue module and is incorporated in the e-fatigue web-based software (https://www.efatigue.com/fatiguecalc.html ). Professor Sehitoglu’s work combined basic mechanics and microstructures enabled him to develop models of the thermomechanical deformation and fatigue processes that predict evolution and failure in high-temperature steels and Ni-base superalloys. He received the best paper presentation award from ASTM (American Society of Testing Materials) for a paper he authored in the area of thermo-mechanical fatigue. Because of his contributions to fatigue he was the plenary speaker at Fatigue 2006 in Atlanta, and gave the Fatigue Lecture of ASTM in Vancouver, Canada, May 2009. More recently, Professor Sehitoglu and his students, with support from Rolls-Royce Corporation and the National Science Foundation, has been modeling the energy of a persistent slip band structure and its stability with respect to dislocation motion as a failure criterion for fatigue crack initiation. The concept of an energy balance and stability of a dislocation structure within a material is not new; it has a long standing historical basis. More importantly this approach allows utilizes atomistic simulations for different grain boundary types. Hence, the atomic simulations provide important insights into the energy barriers and physics of the grain boundaries, which are crucial in explaining not only the lifetimes but their variability with the microstructure. Based on the model Prof. Sehitoglu and his students published several papers, which unequivocally predicts the variation in fatigue lives based on the input data. The work has been recently presented in TMS (Seattle and San Diego) with significant praise. Several engine companies have been interested in the results, and invited them to make presentations on the model. These results will be utilized in constructing an advanced fatigue model for the Air Force Midwest Structural Sciences Center at the University of Illinois.

4. Professor Sehitoglu established the High Temperature Materials Laboratory in the Department of Mechanical and Industrial Engineering. Professor Sehitoglu developed a unique facility with computer controlled test machines for strain, load, environmental (vacuum) and temperature control. He designed a high pressure intensifier to study material behavior at high pressures. In recent years, Professor Sehitoglu expanded the activities to test miniature pumps and thin films. Some of these capabilities are also outlined in the research articles.

5. Professor Sehitoglu served as Director of the Mechanics and Materials Program at the National Science Foundation during 1991-1993. He (with J. Sackman (deceased)) was instrumental in the establishment of the Institute for Mechanics and Materials which had the purpose of bringing the mechanics and materials communities together. The Institute served the community through short courses, workshops, and faculty exchanges. Professor Sehitoglu was also the Engineering Liaison for the agency-wide Materials Synthesis and Processing and Advanced Materials and Processing Program. In these capacities, he worked with teams from other Directorates within NSF.

6. Professor Sehitoglu served as Interim Head of Mechanical Science and Engineering Department during 2004-2005 and was selected as Head of the Department in July 2005. The Department name change to _Mechanical Science and Engineering_ and merger with Theoretical Applied Mechanics Department became effective August 2006. He was instrumental in recruiting over seventeen new faculty in emerging areas of cellular biomechanics, nano-mechanics, dynamics, and fluids over the last five years. The new hires invigorated the MechSE programs with new perspectives and areas of expertise. Professor Sehitoglu, building upon the longstanding strengths of programs in mechanical engineering and in mechanics, led the new MechSE (Mechanical Science and Engineering) Department at Illinois to a bold, new approach to research. He has created an environment that is conducive to integrating biology, chemistry, applied mathematics and applied

27

physics with mechanical engineering and engineering mechanics disciplines. The result has been leading-edge research that serves some of society_s greatest needs, in the areas of energy; disease detection; for cost-effective and non-polluting modes of transportation; for manufacturing solutions that will facilitate the transition of nanoscale discoveries from the laboratory to the public and more. Overall, the result has been to position the department for leadership in a rapidly changing world.

7. As Associate Head within the Department, Professor Sehitoglu was strongly involved in the Faculty Recruiting and Graduate Student Recruiting processes. He secured University funding (through a competition) for graduate fellowships. The number of graduate applications in the nation had decreased following the positive trends in the job market during the 1996-1999 period. Professor Sehitoglu was instrumental in recruitment of highly competitive students to the Graduate Program. When the Mechanical Engineering and Theoretical and Applied Mechanics Departments were merged at Illinois in 2006, he served as the first Department Head of the new department. He was very effective in unifying the collective strengths of both departments, including the combined emphasis on solid mechanics and materials.

8. In his statement on advising, he has stated the following “It has been my intention to prepare all my graduate students and build up their credentials to qualify for an academic position (currently ten of my former PhD students are in academia). Such a preparation would allow them to choose the academic route if they desire. In my field, this means an average of four journal publications, teaching experience, and presentations at conferences are expected. Why do I prefer my students go to academic positions? It allows me to connect with them after graduation through conferences, colloquia and other occasions. It is extremely gratifying to hear the presentations from former students, especially observing some of the styles picked up from Illinois research and at the same time having developed their own approach- it is a proud moment. Of course, I value my former students who went to industry equally but over time, it is difficult to see them. If I were to choose a profession given complete freedom, I would have made the present one as a mentor and professor.“.

9. Professor Sehitoglu prepared a document entitled _Guidelines on Mentoring of New Faculty_ in 2000 after extensive discussions with mentored and mentoring faculty. The purpose of this document has been to review our Department_s mentoring program and to offer guidelines for future mentoring activities. Professor Sehitoglu served as the official mentor for Professors Thomas Mackin and Taher Saif during their tenure track stages and is currently serving as mentor for Alison Dunn.

10. His laboratory on high temperature fatigue and experimentation with shape memory is adopted in industry including control software (Ford, CAT) and inspired other universities (Texas A&M, Georgia Tech.,U.
