Prof. Elias C. Aifantis

Emeritus Professor of Mechanics at Aristotle University of Thessaloniki, Greece
Speech Title: Revisiting Some Basic Concepts & Methods in Advanced Materials

Abstract: Some basic concepts and standard methods that have been used to build recent theories on advanced materials, are revisited by incorporating in the original formulations higher-order gradients, stochasticity and fractal/fractional considerations. Some representative examples are analyzed to show the potential of these ideas to model new phenomena and interpret experimental observations not described by classical theories.

Biography: Elias C. Aifantis is currently an Emeritus Professor of Mechanics at Aristotle University of Thessaloniki/Greece and Michigan Technological University/USA, as well as Mercator fellow at Friedrich-Alexander University/Germany and a Distinguished Professor at Beijing University of Civil Engineering and Architecture/China. Formerly, he has also been a Distinguished Faculty Advisor at King Abdulaziz University/Saudi Arabia, Distinguished Visiting Expert at ITMO University/Russia and Southwest Jiaotong University/China, as well as MegaGrant Director at Togliatti State University /Russia.

He has promoted highly interdisciplinary work in mechanics of materials by bringing into the field of solid mechanics ideas from diffusion theory, chemical reactions, and nonlinear physics. He has coined the terms dislocation patterning, material instabilities, gradient plasticity/elasticity, chemo/nanomechanics, and pioneered internal length gradient (ILG) theories in these fields. Currently, he is extending the ILG framework to revisit electromagnetism and Maxwell’s equations, as well as gravitation and Newton’s Law.

He has published over 339 articles and received about 12,778 citations with 55 h-index (Scopus); 11,963 citations with 54 h-index (Web of Science); 19,750 citations with 69 h-index (Google Scholar). He is included in the ISI Web of knowledge list of the world’s most highly cited authors in engineering.

Speech Title: 2D Transformation Elasticity for Perfect Wave Cloaking

Abstract: While transformation optics and acoustics have made great strides, their elastic counterpart remained impeded by its tensorial character. Indeed, starting with a standard elastic material and applying a curvilinear change of coordinates, the outcome Lagrangian did not seem to correspond to any known elastic materials. This problem is known as “form invariance” (or lack thereof). In this talk, we report on the first designs of elastic materials whose Lagrangians are form invariant. Such materials are “polar” in the sense that they exhibit torque-induced asymmetric Cauchy stresses. They are also “degenerate” in that they admit stressless deformation modes. We explore recent theoretical progress, for conformal transformations in particular, and comment on numerical and experimental demonstrations of invisibility.

Biography: Dr. Guoliang Huang is currently a Huber and Hellen Croft Chair professor of mechanical and aerospace engineering at University of Missouri-Columbia. He received his Ph.D. degree from University of Alberta, Canada, in 2004. Dr. Huang’s research interests include wave propagation and mechanics in elastic/acoustic metamaterials and structural materials, topological and active mechanics, structural dynamics, vibration and sound wave mitigation. Dr. Huang’s research has been funded by NSF, Air Force of Scientific Research, Army Research Office, Office of Naval Research, DURIP, Department of Energy, NASA, and major industries. He has authored one book, 4 book chapters and more than 140 journal papers (include Nature Reviews Materials, Nature Communications, Proceedings of the National Academy of Sciences (PNAS), Advanced Materials, Physical Review Letters, Journal of Mechanics and Physics of Solids, et al.). He serves as associate editor of Wave Motion and specialty chief editor in the Physical Acoustics and Ultrasonics section of Frontiers in Physics.
