Alten F. Grandt is the Raisbeck Distinguished Professor Emeritus at Purdue University's School of Aeronautics and Astronautics. He holds a Bachelor's degree in General Engineering, a Master's degree, and a Ph.D. in Theoretical Applied Mechanics from the University of Illinois at Urbana-Champaign. His primary research interests lie in damage-tolerant structures, materials, fatigue fracture, aging aircraft, and nondestructive inspection techniques. He has engaged in basic research aimed at predicting critical and subcritical crack growth under static and cyclic loads, emphasizing the influence of corrosion on structural integrity. His experimental research is conducted in the Fatigue and Fracture Laboratory and involves computer-controlled electro-hydraulic test machinery to measure fatigue crack formation and propagation. Prof. Grandt has authored numerous publications on various topics, including the prevention of fatigue failure and lessons learned from aerospace failures. He has been recognized with several awards, including the Distinguished Alumni Award from his alma mater and the AIAA Fellow J.W. Lincoln Award for contributions to aircraft structural integrity.
