Daniel C. Drucker
Daniel Charles printer ( * 1918 in New York City; † 1 September 2001 in Gainesville, Florida ) was an American engineer scientist who is well known for contributions to the theory of plasticity and photoelasticity.
Life
Printer studied civil engineering at Columbia University and in 1940 received his doctorate in Raymond D. Mindlin on photoelasticity. He then taught until 1943 at Cornell University, before joining the Armour Research Foundation ( at the Illinois Institute of Technology) and served in the U.S. Air Force in World War II. From 1947 he was at Brown University, where he partially carried out his seminal work on the theory of plasticity with the local Professor William Prager. From 1968 he was dean of engineering at the University of Illinois. From 1984 he was a professor at the University of Florida, where he retired in 1994.
In the theory of plasticity, the Drucker-Prager model and the printer Stability postulate is named after him. He turned the theory of plasticity in both metals as well as in soil mechanics, where he worked with David Henkel in the interpretation of its basic triaxial tests on clay.
He was 1981/2 President of the American Academy of Mechanics (AAM ) and also President of the International Union of Theoretical and Applied Mechanics, the American Society of Mechanical Engineers (ASME ), the Society for Experimental Mechanics (SEM) and the American Society for Engineering Education ( ASEE ). He received the von Karman Medal of the American Society of Civil Engineers ( ASCE ). In 1988 he received the National Medal of Science, the Timoshenko Medal of the ASME, the Egleston and Ilig Medal of Columbia University and in 1983 he received the first William Prager Medal. He was more honorary doctorates, including Brown University, the Technion, the University of Illinois at Urbana- Champaign. Printer was a member of the American Academy of Arts and Sciences, the National Academy of Engineering and a foreign member of the Polish Academy of Sciences. He was an honorary member of the ASME and the SEM.
For twelve years he was editor of the Journal of Applied Mechanics.
He was married from 1939 until her death in 2000, Ann Bodlin, with whom he had a son and a daughter.
Daniel C. printer Medal
It is given in his honor since 1998 by ASME.
