Description | Citation typed |
Citation | John Knott is distinguished for his contributions to the quantitative scientific understanding of fracture processes in metals and alloys and its applications in engineering. In particular he has elucidated the role of microstructure in the initiation and propagation of cracks and shown how criteria based on this understanding can allow the design of structures which are tolerant to defects in service. His work has involved detailed analysis of the micromechanisms of ductile, fatigue and brittle fracture modes in many types of steel and non-ferrous alloys, using innovative techniques of mechanical testing which allowed detailed monitoring of crack propagation. His work on stress relief cracking, on ductile crack initiation in pressure vessel steels, and on fracture processes at and near welded joints has been of substantial importance in establishing codes of safe practice. His contributions are characterised by the application of diverse techniques to a very wide range of fracture problems, which he has analysed ably to provide models of the fracture process, exhibiting a full understanding of both the engineering and metallurgical principles involved. He is author of a much-used text book on fracture mechanics. |
