Dr. Alain Karma - Phase-field modeling in materials science
Wednesday, September 11, 2019 at 3:00pm to 4:00pm
Building 1, 190
33 MASSACHUSETTS AVE, Cambridge, MA 02139
This talk is part of a 3-day mini-summit through DMSE. Please join us on Sept. 10 and 12 for more events!
This talk will provide an overview of the use of coarse-grained phase-field models as fruitful theoretical frameworks and computational tools for predicting materials structures and behavior on length and time scales that generally fall in between those accessible by atomistic scale and macroscale continuum simulations. Recent progress and challenges will be summarized in the historical context in which phase-field models have been developed and used to simulate nano/microstructural pattern formation in diverse materials synthesis applications (from nanocrystalline growth to alloy solidification), crystal defect and grain boundary dynamics on diffusive time scales enabled by the advent of the phase-field-crystal method, and fracture exemplified by applications to failure of biomimetic materials and chemo-mechanical failure of battery materials.
