明平兵,中國(guó)科學(xué)院數(shù)學(xué)與系統(tǒng)科學(xué)研究院研究員,目前擔(dān)任《數(shù)值計(jì)算與計(jì)算機(jī)應(yīng)用》主編。主要從事固體多尺度建模、模擬及科學(xué)機(jī)器學(xué)習(xí)方面的研究,在Cauchy-Born法則的數(shù)學(xué)理論以及石墨烯理想強(qiáng)度的理論預(yù)測(cè)領(lǐng)域做出了突出工作;于2014年獲得國(guó)家杰出青年基金、2019年入選第四批國(guó)家“萬(wàn)人計(jì)劃”中青年科技創(chuàng)新領(lǐng)軍人才計(jì)劃,2023年獲第十五屆“馮康科學(xué)計(jì)算獎(jiǎng)”;2024年當(dāng)選中國(guó)工業(yè)與應(yīng)用數(shù)學(xué)學(xué)會(huì)會(huì)士。曾應(yīng)邀在SCADE2009,The SIAM Mathematics Aspects of Materials Science 2016等會(huì)議上作大會(huì)報(bào)告。
報(bào)告摘要:
We shall discuss two topics in the numerical homogenization. 1) Heterogeneous multiscale method (HMM) for general medias that includes the stratified media and the quasi-periodic media, an online-offline method 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).
