Professor Juri Estrin

Honorary Professorial Fellow
Department of Materials Science and Engineering

Professor Yuri Estrin’s research interests are focusing on the mechanical properties of metallic materials, particularly on modelling the mechanical response by using fundamental concepts of crystal plasticity and dislocation theory. The ultimate goal of this research is to equip the engineers with physically sound, yet sufficiently simple and user-friendly modelling tools that can be applied for efficient simulations of metal forming operations and the product performance under service conditions. He is participating in various projects aiming at improving the properties of Al, Mg and Ti based light alloys. A particular aim of his research is producing ultrafine grained light alloys that can be used as superior structural materials. By applying special severe plastic deformation techniques, materials with unique properties are produced. In addition to this work on light alloys, Prof. Estrin is also involved in projects on ferrous materials. Strength and plasticity of nanomaterials is a further area to which he is dedicating a great deal of his research activities. His interest in nanomaterials goes beyond their mechanical properties, though: such aspects as suitability of nanostructured metals for applications in hydrogen storage systems, biomedical implants and micro-electro-mechanical systems (MEMS) are also a significant part of his research. An entirely different area Professor Estrin works in is geometry-inspired design of novel, ‘architectured’ materials (archimats). Using geometry principles, segmented structures can be produced, with individual ‘building blocks’ being interlocked and arrested by virtue of their geometry and arrangement only – that is, without any connectors or binder. Such archimats exhibit very unusual properties, including enhanced resistance to crack propagation, exceptionally great tolerance to local failures and controllable stiffness, which opens up interesting new avenues in materials design. Professor Estrin’s research on archimats has been presented in a book on “Architectured Materials in Nature and Engineering. Archimats” he co-edited: https://www.springer.com/gp/book/9783030119416.
