Шаблон:Use dmy dates Шаблон:Use British EnglishШаблон:Infobox scientist Andrew Noel Schofield FRS[1] FREng[2] (born 1 November 1930) is a British soil mechanics engineer and an emeritus professor of geotechnical engineering at the University of Cambridge.
Life
Schofield was born on 1 November 1930, the son of Rev John Noel Schofield and Winifred Jane Mary Eyles in Cambridge, England. He married Margaret Eileen Green in 1961.Шаблон:Sfn He retired from Cambridge University in 1997.
Career
Andrew Schofield studied engineering and graduated from Christ's College, Cambridge in 1951.Шаблон:Sfn He then worked in the Nyasaland Protectorate, Africa (now Malawi) office of Scott and Wilson Ltd. where he performed research on lateritic soils and low cost road construction.Шаблон:Sfn He returned to Cambridge University to work with Professor Kenneth H. Roscoe on his PhD, which he completed in 1961.Шаблон:Sfn He became an Assistant Lecturer in 1961 and a Fulbright Fellow and a California Institute of Technology Fellow in 1963/4.[3] He was elected Fellow of Churchill College, Cambridge in 1964.[4] He was elected as a Fellow[5] of the Royal Academy of Engineering[6] in 1986 and as a Fellow of the Royal Society in 1992.[7]
With Ken Roscoe and Peter Wroth in 1958 he published "On the Yielding of Soils", which showed how plasticity theory and critical state soil mechanics could be used to describe the coupled volumetric and shear behavior of soils.Шаблон:Sfn This led to the development of a constitutive model known as 'Cam Clay' that was formalized in a text by Schofield and Wroth in 1968.Шаблон:Sfn
Schofield was influenced by work on geotechnical centrifuge modeling by G.I. Pokrovsky in the USSRШаблон:Sfn to study geotechnical engineering and soil mechanics problems. He developed a prototype geotechnical centrifuge in Cambridge and later adapted a centrifuge in the English Electric Company in Luton, UK, to be used for geotechnical modelling in 1966.Шаблон:SfnШаблон:Sfn
He accepted a chair at the Institute of Science and Technology in Manchester (UMIST) in 1968 and developed a 1.5-m radius geotechnical centrifuge there.Шаблон:SfnШаблон:Sfn Following Roscoe's death in 1970, he returned to Cambridge in 1974 and was appointed as a Professor in the Cambridge University Engineering Department to lead the Soil Mechanics group.Шаблон:Sfn Working with the mechanical design engineer Phillip Turner, he developed a 5-m radius geotechnical centrifuge at Cambridge University that continues to be heavily used as of 2010. He was elected a Fellow of the Royal Society in 1992. Schofield retired from the university in 1997, but his continued work is evidenced by the publication of a book in 2005.Шаблон:Sfn
Critique of The Mohr Coulomb equation as foundations in soil mechanics
By Professor Schofield the behaviour of remoulded soil (be it sand, silt or clay) is governed by friction and particle interlocking. By Professor Schofield, The Mohr Coulomb equation, popularised by Terzaghi, and underpinning developments in soil mechanics since the 1930s, is simply wrong. Terzaghi made soil mechanics a science, made a mistake when he said soil’s strength is provided by cohesion and friction.[8]
