Kenneth Langstreth Johnson (19 March 1925 – 21 September 2015) was a British engineer, Professor of Engineering at the University of Cambridge from 1977 to 1992 and a Fellow of Jesus College, Cambridge.[2] Most of his research was in the areas of tribology. He is known for developing the JKR model of contact mechanics.
Education
[edit | edit source]Johnson was educated at Barrow Grammar School and the University of Manchester where he was awarded MScTech, Master of Arts and Doctor of Philosophy degrees supervised by H. Wright Baker.[3]
Awards and honours
[edit | edit source]Johnson was elected a Fellow of the Royal Academy of Engineering in 1987,[4] a Fellow of the Royal Society (FRS) in 1982[1][5] and won their Royal Medal in 2003[6] "In recognition of his outstanding work in the field of contact mechanics." His 1971 paper[7] with Kevin Kendall and Alan D. Roberts forms the basis of modern theories of contact mechanics.[8] He also made significant contributions to the understanding of fluid rheology under elastohydrodynamic lubrication conditions.[9]
He received the International Award from the Society of Tribologists and Lubrication Engineers in 1983.[10] He was awarded the Tribology Gold Medal from the Institution of Mechanical Engineers in 1985.[11] He was awarded the Mayo D. Hersey Award from the American Society of Mechanical Engineers in 1991.[12] In 1999, Johnson won the William Prager Medal awarded by the Society of Engineering Science.[13] He was also awarded the 2006 Timoshenko Medal.[14]
He died on 21 September 2015.[2][4]
