Fazil Erdoganis a Professor emeritus of Mechanical Engineering and Mechanics and Dean emeritus of the College of Engineering at Lehigh University. Dr. Erdogan graduated with an M.S. from Istanbul Tech. in Turkey in 1948 before coming to Lehigh for his Ph.D. in 1955. He began teaching in 1957 and was named the G. Whitney Snyder professor emeritus in 2001. During his tenure at Lehigh, Professor Erdogan was well-respected by, and an inspiration to his students and peers.

He was awarded the Eleanor and Joseph F. Libsch Research Award in 1982. The award is given to faculty members who demonstrate scholarly excellence, have caused Lehigh to gain significant recognition in their chosen fields, and have made at least one major research accomplishment in the five years preceding their receipt of the award. Dr. Erdogan also received the Hillman Faculty Award in 1993 for his excellence and dedication to graduate advising.


Erdogan is known throughout the world for his work in fracture mechanics. In the 1960s and 70s, he and his students developed the first analytical approaches and solution techniques for the formulation and reduction of fracture mechanics problems involving layered media to systems of singular integral equations. His research in this area has enabled countless sectors within materials industries to develop new ways of monitoring the safety and effectiveness of their products.

Other Awards and Recognitions

He was awarded the A.C. Eringen Medal from the Society of Engineering Sciences in 1993. In 1997, Dr. Erdogan was chosen for membership into the National Academy of Engineering. He is a two-time recipient of the German, Alexander von Humboldt Foundation Senior Scientist Award. He is widely published and has received grants from NASA, the National Science Foundation, and other sources totaling over $1,200,000. He has also served on the advisory board of the Turkish Journal of Engineering and Environmental Sciences. Erdogan has served as a visiting professor at universities in Germany and the Technical University of Denmark, and as a visiting research scientist and DuPont Co.

He is a Fellow of the American Society of Mechanical Engineers (ASME) and a member of the Lehigh chapter of Sigma Xi, the Scientific Research Society. In September 2008, the Journal of Applied Mechanics published a special issue honoring Dr. Erdogan's contributions to the field of fracture mechanics. The issue consists of thirteen original papers dedicated to the mechanics of inhomogeneous and functionally graded materials. Many of these articles were written by his former students and colleagues. This issue is based on an October 2006 symposium in Honolulu, Hawaii entitled the International Conference on Multiscale and Functionally Graded Materials.
