报告题目: Certain critic Issues in Multiscale Modeling and Methods in Solids: Numerical Analysis' Viewpoint
报告概况: Multiscale modeling and simulation have been quite popular in many fileds for almost two decades. In tis talk, I will discuss several critical issues in multiscale modeling and simulation, in particluar for crystalline solids. Cauchy-Born rule and quasicontinuum method are used as show-case. The former is the bridge between the atomistic model and the continuum mechanics model for crystalline solids, while the latter is among the most popular multiscale method for modeling the elastically deformation of the crystalline solids. On the one hand, we shall discuss the validation of Cauchy-Born rule and the accuracy of quasicontinuum method in the framework of the classical numerical analysis. On the other hand, we shall discuss the limitation of the classical numerical analysis framework when applied to multiscale modeling.
