Biography:
Professor Anthony Kelly is an Emeritus Professor and Distinguished Research Fellow at Cambridge.

He is a Fellow of the Royal Society, a Fellow of the Royal Academy of Engineering and a Foreign Associate of the US National Academy of Engineering. He is a Fellow of the Institute of Physics, a Fellow of the Institution of Materials Mining and Metallurgy (and past President) as well as being a founding Fellow of Churchill College Cambridge. He holds Honorary Degrees from Universities in Europe, the USA and Korea.

He is an Honorary Fellow of the Institute of Linguists, of the Institution of Civil Engineers and of the Institution of Structural Engineers.

He has been employed in Universities, in Government Science (National Physical Laboratory) and in industry (ICI). He was Vice-Chancellor of the University of Surrey from 1975 until 1994. While there he established the Surrey Research Park and was the first chairman of Surrey Satellite Technology Ltd.

His early scientific work related x-ray and electron microscope studies of precipitation and dispersion hardened alloys and in 1963 with Robin Nicholson ( now Sir Robin) produced the first synthesis, which has stood the test of 50 years, relating type of dispersion and work hardening characteristics of metals. This has become an SCI citation classic.

He pointed out clearly the nature of the criterion for metals to show polycrystalline ductility by glide and applied this to important ceramic and other inorganic materials which were becoming available in the 60s and 70s. He applied the same ideas to the climb of dislocations. This led to a criterion for distinguishing fundamentally between brittle and ductile crystals and to detailed calculations of the ideal strength of crystals.

He set down the principles of the materials science of metallic composite materials, particularly the strength, toughness and creep of short fibre composites, and led the way to relating fibre reinforcement and conventional strengthening methods of metals. This was followed by the experimental analysis of fibre bundle failure. His group explored for the first time the phenomenon of multiple fracture of a fibrous composite in detail which explained the properties of fibre reinforced cements and concretes and which has led to the whole development of ceramic composite materials as well as to an understanding of the modes of toughness of laminated composite structures with resin matrices. For this work and for his books and editing of a number of treatises on composites he has been called 'The Father of Composite Materials'.

In the 1990s he established the fundamental limits to the attainable packing density of assemblies of long straight fibres and supported this with experiment in order to establish the most possible dense packing of random fibre arrangements and of those regular fibre arrangements which can produce elastic isotropy.

Since 2000 his principal interest is in using composite principles to control and to modify the thermal expansion coefficients of materials so as to obtain hitherto unattained values and to obtain these with a desirable combination of other properties. He has lately turned his interests to understanding the science of climate.

Kelly has worked for periods in the USA, Germany and in Switzerland. He has an interest in the linguistic aspects of science and is an Honorary Fellow of the Institute of Linguists.

From 1988 until 1997 he was Chairman of the Standing Committee on Structural Safety of the Institutions of Civil and of Structural Engineers, which was reconstituted under his Chairmanship to include the Health and safety Executive.
