Abstract:
The performance and reliability of industrial components and structures depend to a great extent on the mechanical, physical and functional properties of the materials involved. Industrial sectors such aeronautics depend heavily on material and structural developments and innovation to maintain a leading technological edge in a highly competitive world stage. In a world where the notion of performance has progressively given way to that of reliability and environmental protection, it will be shown that the behaviour of materials is still controlled by their compositions, processing routes and by their thermo-mechanical transformations which need to be optimised. Thus the control of materials lies on the processing methods used and on the understanding and prediction, by way of sophisticated modelling tools, of their behaviour under conditions as close as possible to those seen in service. In this lecture, an overview of the role of materials and structures in the aeronautical industry will be presented. In particular, a historical description of the role and importance of structural materials in aeronautics will be given. This will include examples of how materials and structural concepts have defined the way in which airplane designs have evolved through the years, the loading conditions that critical components of current and next generation of gas turbine aero-engines are subjected to, and typical failure modes. It will be shown that recent outstanding developments in materials science and technology and structural reliability are the result of a real multidisciplinary collaboration between metallurgists, engineers, physico-chemist, physicists and material scientists.
Biography:
Esteban Busso is currently visiting professor of Imperial College London and working at MATTech International R&D Consulting. From 2013 till 2017 he was the Scientific Director of ONERA's Materials and Structures Branch. From 2005 till 2013 he was a Professor of Mechanics of Materials at the Ecole des Mines de Paris and Director of the Ecole's Centre des Matériaux and, from 1994 till 2005, Professor at Imperial College's Department of Mechanical Engineering in London, UK. Dr. Busso obtained his undergraduate degree from the University of Cordoba, Argentina, in Dec. 1980. In 1985, he joined the Massachusetts Institute of Technology (MIT) in Cambridge, USA, where he was awarded his MSc degree and, in 1990, his PhD degree in Mechanical Engineering. He has also worked in industry in the UK, Japan, South Africa and Argentina. His research involves micromechanics studies of deformation and fracture of materials and interfaces, with an emphasis on the development of multiscale and multiphysics concepts in mechanistic models to predict deformation and fracture processes. In August 2014, Dr. Busso was elected to the British Royal Academy of Engineering. He has authored and edited 12 scientific books, and published over 135 articles in peer reviewed international journals (H-index of 32 with 3205 citations in Google Scholar). He is an advisor to industry worldwide, to the US Department of Energy, the European Commission, as well as the British, Dutch and French research councils, amongst others.
