建立了纳米级连续介质理论，直接将原子间势纳入连续介质分析中，无需任何参数拟合。该理论将材料的原子间势和原子结构与连续体水平上的本构模型联系起来。该理论应用于研究单壁碳纳米管的线弹性模量。这种纳米级连续介质理论预测的杨氏模量与先前的实验结果和原子研究非常吻合。
A nanoscale continuum theory is established to directly incorporate interatomic potentials into a continuum analysis without any parameter fitting. The theory links interatomic potentials and atomic structure of a material to a constitutive model on the continuum level. The theory is applied to study the linear elastic modulus of a single-wall carbon nanotube. The Young's modulus predicted by this nanoscale continuum theory agrees well with prior experimental results and atomistic studies.
