DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GSMMA/11/">G
 rain structure\, grain growth and evolution of the grain boundary network 
 in polycrystalline materials: theory\, simulations\, and experiments</a>\n
 by Yekaterina Epshteyn (The University of Utah) as part of Global Seminar 
 on Mathematical Modeling and Applications\n\n\nAbstract\nMost technologica
 lly useful materials are polycrystalline microstructures\ncomposed of myri
 ad small monocrystalline cells/grains separated by grain\nboundaries/inter
 faces. Grains and grain boundaries play a crucial role in\ndetermining the
  properties of materials across multiple scales.\n\nOne method by which th
 e grain structure is engineered is through grain\ngrowth or coarsening of 
 a starting structure. Grain growth can be viewed\nas the evolution of a la
 rge metastable network\, and can be mathematically\nmodeled by a set of de
 terministic local evolution laws for the growth of\nan individual\ngrain c
 ombined with stochastic models to describe the interaction between\ngrains
 . Thus\, to develop a predictive and prescriptive theory for\npolycrystall
 ine materials\, investigation of a broad range of statistical\nmeasures fo
 r microstructure evolution during grain growth is needed. In\nthis talk\, 
 we will discuss recent progress on modeling\, simulation\,\nanalysis and e
 xperiments of the evolution of the grain boundary network in\npolycrystall
 ine materials.\n
