Johannes Weertman

from Wikipedia, the free encyclopedia

Johannes Weertman (born May 11, 1925 in Fairfield , Alabama , † October 13, 2018 ) was an American materials scientist and geophysicist .

Life

Weertman studied at the Carnegie Institute of Technology with a bachelor's degree in 1948 and a doctorate in physics in 1951. As a post-doctoral student he was a Fulbright Fellow at the École normal supérieure in Paris. He was then from 1952 at the US Naval Research Laboratory and from 1959 first associate professor and then professor at Northwestern University. In 1963 he became professor for geophysics and from 1968 Walter P. Murphy professor for materials science.

He was a consultant at Los Alamos National Laboratory from 1967 to 1991 , a visiting scientist at Caltech in 1964 , a consultant to the US Army Cold Regions Research and Engineering Laboratory from 1960 to 1975, and he was a consultant to the Bain Laboratory of the US Steel Corporation and the Oak Ridge National Laboratory. In 1986 he was a visiting scientist at the Swiss Reactor Research Institute and in 1971/72 at the Scott Polar Research Institute in Cambridge.

He dealt with flow in crystals and the theory of dislocations , glacier dynamics and other problems in geophysics (e.g. the spread of dislocations in earthquakes), metal physics, internal friction, fatigue fractures and fracture mechanics.

He was a Fellow of the American Academy of Arts and Sciences (1997), the American Association for the Advancement of Science , the American Geophysical Union , the American Academy of Mechanics, the American Physical Society, and the National Academy of Engineering . In 1970/71 he was a Guggenheim Fellow. In 1962 he received the Horton Award from the American Geophysical Union, in 1977 the Matthewson Gold Medal from the American Institute of Mining, Metallurgy and Petroleum Engineering, in 1983 the Seligman Crystal Award from the International Glaciological Society and in 1980 the Gold Medal from Acta Metallurgica.

Weertman Island in Antarctica is named after him. Weertman was married to Julia Randall Weertman (1926-2018, Professor of Materials Science at Northwestern University and physicist) since 1950 and has a son and a daughter.
