Abstract: The bridging between the behaviour of a material at different microstructural scales remains a topic of major interest and is at the heart of multiscale modelling schemes developed to predict the behavior of microstructurally heterogeneous materials. Multiscale materials modeling has been a topic of significant interest in the materials, mechanics and physics communities for a number of years, largely due to the demonstrated value of robust, accurate, predictive simulations of materials behavior in enabling a mechanistic understanding of advanced materials and manufacturing processes. There are many challenges, however, that must be addressed to achieve true integration and linkage of materials models and simulations across length and time scales. This includes the need to develop fundamental linkage models, implement strategies, and reduce computational cost.

The aim of this seminar is to discuss the current state of the art in this field, including gaps and limitations, and outline future perspectives and opportunities. An overview of some key models within given length scale regimes, related well-known software packages, and of some current state-of-the-art methods for linking across scales are presented.

Brief Introduction of Speaker
ESTEBAN P. BUSSO

Esteban Busso is currently Professor of Micromechanics and a National 1000 Talent Award Holder at the Harbin Institute of Technology, in Shenzhen, China, where he was Chief Academic Advisor from June 2018 to March 2019. He is also Scientific Advisor at the Centre of Excellence for Advanced Materials (CEAM), in Dongguan, and at the East China University of Science and Technology, in Shanghai, China, and Invited Professor at Imperial College’s Department of Mechanical Engineering, in London, UK. He was till May 2018, the Scientific

Director of the National Aerospace Research Centre of France (ONERA) (approx. 2000 permanent staff) in the areas of Materials and Structures. 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. In August 2014, Dr. Busso was elected a Fellow of the British Royal Academy of Engineering. In March 2019, he was awarded China’s National 1000 Talent Plan Professorship (Topnotch Talents Category), the highest academic honour in China to recognise leading international experts in scientific research. He is a Fellow of the British Institute of Materials, Minerals and Mining and of the Societé Francaise des Matériaux, a Chartered Engineer in the UK and a member of the Royal Academy’s Aerospace Committee. 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. He is currently an Editorial Board member of Philosophical Magazine , the Journal of Multiscale Modelling, the Journal of Mechanical Behavior of Materials, and the Journal of Materials Discovery , and was a former associate editor of the ASME Journal of Eng. Materials and Tech. and the Aerospace Lab Journal, and an Editorial Board member and guest editor of the Int. Journal of Plasticity . He has authored and edited 12 scientific books, and has published over 135 peer-reviewed articles (H-index of 35 with 3836 citations in Google Scholar). He has also organised or co-organised 13 international conferences and more than 16 international symposia in the field of mechanics of materials, and has taught materials and mechanics courses at the undergraduate and the graduate level for over 25 years. He is an advisor to industry worldwide, to the US Department of Energy, the European Commission, the European Research Council, as well as the British, Dutch and French research councils, amongst others.
