Acoustic Emission and Related Non-destructive Evaluation Techniques in the Fracture Mechanics of Concrete

Dr. Masayasu Ohtsu is an adjunct professor at the Laboratory on Innovative Techniques for Infrastructures, Kyoto University, Japan and an emeritus professor of the Kumamoto University, Japan. His major research field contains applications of acoustic emission to concrete, nondestructive evaluation of concrete structures and numerical analysis of composite structures.
