Georges Ayoub, Ph.D.

Dr. Ayoub research interests encompass characterizing processed materials and establishing models that can predict the material response and hence guide the design of materials through processing to be used for manufacturing purposes and for in-service performance, that are of interest to transportation, defense, energy, aerospace, biomedical and oil and gas industries. Topics of interest: fracture and fatigue of polymers and composites; welding; metal forming; additive manufacturing; nano-multilayer composite coatings design and modeling;thermo-mechanical processing; fatigue and fracture.
