P. S. Theocaris

P.S. Theocaris was a legendary figure in the mechanics community in Greece. He also was one of the most outstanding experimental stress analysts in the world during the second half of the twentieth century. He was member of the Academy of Athens, the most prestigious distinction of professionals in Greece. He also served as corresponding or, foreign member to other Academies in Europe. He was the recipient of many awards and distinctions. He was elected as SEM Fellow in 1979. As an experimentalist, he is known primarily for his work in moiré, photoelasticity and caustics.


The award in question is designed to recognize a senior individual for distinguished, innovative and outstanding work in optical methods and experimental mechanics.
