Young's modulus of Graphene: a molecular dynamics study主要由Jiang, Jin-Wu、Wang, Jian-Sheng、Li, Baowen编写,在2009年被收录,
Young's modulus of CNT represents a high dependency of stiffness on tube thickness, while dependency on tube diameter is more tangible for smaller tube diameters. The presented closed-form solution provides an insight to evaluate finite element models constructed by beam elements. The results are ...
