报告简介:
Anisotropic and layered systems exist in nanoscale quantum devices as well as in conventional macroscale structures. There are natural and manmade anisotropic and layered structures. These structures are grown or fabricated for special property demands. Yet, material anisotropy and layering pose great challenges both theoretically and computationally, and so far no reliable modeling tool is available for these complicated yet extremely useful structures.
In this talk, I will first briefly review the current research works being carried out in my group. These include multilayered flexible pavements, quantum nanostructures (quantum wells, wires, and dots) and multiphase (particularly multiferroic) materials and composites. I will then present some fundamental dislocation solutions in 2D and 3D full, half, and bimaterial spaces. Numerical examples will be given for dislocation arrays in anisotropic layered plates and dislocation dipoles in wire composites.
