Topic: Multi-scale/physics mechanics in functional material structures and advanced manufacturing
Speaker: Prof. Yi Min, College of Aerospace Engineering, Nanjing University of Aeronautics and Astronautics (NUAA)
Time: Saturday, May 8, 3:00 PM
Venue: C708, New Main Building
Both functional materials and advanced manufacturing have multi-physical field coupling properties such as force, electricity, magnetism, heat, and light, and their macroscopic properties are closely related to the multi-scale micro-structure. Mechanical modeling and calculations considering the properties of microstructures and multi-field coupling have become an important part of the design and development process of functional material and advanced manufacturing. The presenter will report the results of recent years' research on multi-scale/physics mechanics in functional materials and advanced manufacturing, including 1) force-magnetic coupled phase-field models of microstructure evolution and fracture in ferromagnetic materials; 2) multi-scale calculations of the temperature dependence of solid magnetic properties across electron/spin-atomic spin-continuum media; 3) phase-field modeling and multi-scale calculations of magneto-thermal/elastic thermal effects; 4) microstructure evolution and magnetic properties of ferromagnetic materials in selective laser melting additive manufacturing; and 5) multi-field coupled modeling and calculation of microstructure evolution in powder advanced manufacturing.
