報告人簡介:明平兵,國家級人才,中國科學(xué)院數(shù)學(xué)與系統(tǒng)科學(xué)研究院研究員,科學(xué)與工程計算國家重點實驗室副主任,主要從事固體多尺度建模、模擬及多尺度算法的研究。他預(yù)測了石墨烯的理想強度并在Cauchy-Born法則的數(shù)學(xué)理論、擬連續(xù)體方法的穩(wěn)定性方面有較為系統(tǒng)的工作。他在JAMS, CPAM, ARMA, PRB, JMPS, Acta Materialia, SINUM, Math. Comp, Numer. Math等國際著名學(xué)術(shù)期刊上發(fā)表學(xué)術(shù)論文六十余篇。他曾應(yīng)邀在SCADE 2009、The SIM Mathematics Aspects of Materials Science 2016等會議上作大會報告。
報告摘要:We shall discuss two topics in the numerical method for multiscale PDEs, which concern the heterogeneous multiscale method (HMM). 1) The first topic is HMM for general medias that includes the locally periodic media and the quasi-periodic media, an online-offline strategy shall be discussed for the localized defects; 2) Representative volume element for the strain gradient elasticity model for heterogeneous media, which is a typical representative for the higher order elliptic system. This is a joint work with Si Qi Song (AMSS) and Yulei Liao (National University of Singapore).
