Anthony Ingraffea, PhD, PE

Dr. Ingraffea is the Dwight C. Baum Professor of Engineering Emeritus at Cornell University, where he taught structural mechanics, finite element methods, and fracture mechanics at Cornell for 37 years. Dr. Ingraffea's research concentrates on computer simulation and physical testing of complex fracturing processes. He and his students performed pioneering research in using interactive computer graphics in computational mechanics, and together they authored more than 250 papers in these areas. He has been a principal investigator on more than $37 million in R&D projects from the NSF, NASA, Nichols Research, AFOSR, FAA, Kodak, U. S. Army Engineer Waterways Experiment Station, U.S. Dept. of Transportation, IBM, Schlumberger, EXXON, the Gas Research Institute, Sandia National Laboratories, the Association of Iron and Steel Engineers, General Dynamics, Boeing, Caterpillar Tractor, and Northrop Grumman Aerospace. For his research achievements he has won the International Association for Computer Methods and Advances in Geomechanics "1994 Significant Paper Award" for one of the five most significant papers in the category of Computational/Analytical Applications,  twice won the National Research Council/U.S. National Committee for Rock Mechanics Award for Research in Rock Mechanics (1978, 1991), and the George Irwin Medal form the American Society for Testing and Materials (2006). He was named a Fellow of the International Congress on Fracture in 2009. He is Co-Editor-in-Chief of the premier journal in his field, Engineering Fracture Mechanics.
