Abstract:

Multiscale and multiphysics materials modeling tackles the challenging materials problems that involve multiple physical phenomena at multiple spatial and temporal scales. In this talk, I will present  the multiscale and mulphysics models developed in my research group with a recent focus on energy storage materials and advanced structure materials. Our study of rechargeable lithium ion batteries for energy storage applications reveals a rich spectrum of electrochemically-induced mechanical degradation phenomena. The work involves a tight coupling between multiscale chemomechanical modeling and in situ nanobattery testing. Our study of nanostructured metals and alloys elucidates the effects of nanostructures on the size-dependent strengths and surface/interface-mediated deformation mechanisms. Finally, I will present our recent studies of high entropy alloys and additively manufactured materials.  Overall, our research synergistically integrates modeling and in situ experiment in order to design the advanced structural and functional materials to realize their potential to the full.
