Dwight C. Baum Professor of Engineering
Weiss Presidential Teaching Fellow
School of Civil and Environmental Engineering
Cornell University, Ithaca, New York USA 14853              

Ph.D., Civil Engineering, University of Colorado/Boulder, 1977, University Fellow.
M.S., Civil Engineering, Polytechnic Institute of New York, 1971, Grumman Masters Fellow.
B.S., Aerospace Engineering, University of Notre Dame, 1969, magna cum laude.




Dr. Ingraffea’s research concentrates on computer simulation and physical testing of complex fracturing processes.  He and his students performed pioneering research in the use of interactive computer graphics and realistic representational methods in computational fracture mechanics.  He has authored with his students and research associates over 250 papers in these areas, and he is Director of the Cornell Fracture Group (

Since 1977, he has been a principal or co-principal investigator on over $35M in R&D projects from the National Science Foundation, NASA Langley, Nichols Research, NASA Glenn, Air Force Office of Scientific Research, Federal Aviation Administration, Kodak, U. S. Army Engineer Waterways Experiment Station, U.S. Dept. of Transportation, IBM, Schlumberger, Gas Technology Institute, Sandia National Laboratories, the Association of Iron and Steel Engineers, General Dynamics, Boeing, Caterpillar Tractor, Defense Advanced Research Projects Agency, and Northrop Grumman.

Professor Ingraffea was a member of the first group of Presidential Young Investigators named by the National Science Foundation in 1984. For his research achievements in hydraulic fracturing he has won the International Association for Computer Methods and Advances in Geomechanics "1994 Significant Paper Award" for one of five most significant papers in the category of Computational/Analytical Applications in the past 20 years, and he has twice won the National Research Council/U.S. National Committee for Rock Mechanics Award for Research in Rock Mechanics (1978, 1991). He became a Fellow of the American Society of Civil Engineers in 1991, and named the Dwight C. Baum Professor of Engineering at Cornell in 1992.   His group won a NASA Group Achievement Award in 1996, and a NASA Aviation Safety /Turning Goals into Reality Award in 1999 for its work on the aging aircraft problem. He became Co-Editor-in-Chief of Engineering Fracture Mechanics in 2005. In 2006, he won ASTM’s George Irwin Award for outstanding research in fracture mechanics, and in 2009 was named a Fellow of the International Congress on Fracture.  TIME magazine named Dr. Ingraffea one of its “People Who Mattered” in 2011 for his work in public education on the issue of unconventional development of natural gas from shale formations.
