| Title: Revisiting the Classical Laws of Material Mechanics | |
| Abstract: Motivated by van der Waals gradient theory of interfaces and Ginzburg-Landau order parameter theory of interfaces, an effort has started 40 years ago to extend Hooke's law of elasticity and von Mises flow rule of plasticity, by including nonlocality and examine the implications on removing the classical, but undesirable, singularities from dislocations lines and crack tips, as well as interpreting size effects. These developments are reviewed within a recent proposal for internal length gradient (ILG) mechanics. Moreover, a suggestion is advanced for a gradient modification of Newton's law of gravity and Coulomb's law of electrostatics. References E.C.

| 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 11,704 citations with 54 h-index (Scopus); 10,832 citations with 53 h-index (Web of Science); 17,860 citations with 66 h-index (Google Scholar). He is included in the ISI Web of knowledge list of the world’s most highly cited authors in engineering. | |
