Formation of Non-uniform Double Helices for Elastic Rods under Torsion
Hongyuan Li, Shumin Zhao, Minggang Xia +4
The spontaneous formation of double helices for filaments under torsion is common and significant. For example, the research on the supercoiling of DNA is helpful for understanding…
Conformation characters of gel sheets with rotational symmetry: the role of boundary
Xiaobo Zhai, Shengli Zhang, Shumin Zhao
In this paper, we systemically study the conformation characters of rotational symmetric gel sheets with free boundary and investigate the role of boundary on the equilibrium confo…
Equilibrium conformation of polymer chains with noncircular cross section
Shumin Zhao, Shengli Zhang, Zhenwei Yao +1
In this paper we derive the general equilibrium equations of a polymer chain with a noncircular cross section by the variation of the free energy functional. From the equilibrium e…
Buckling and competition of energy and entropy lead conformation of single-walled carbon nanocones
Shengli Zhang, Zhenwei Yao, Shumin Zhao +1
Using a continuum model, expressions for the elastic energy, defect energy, structure entropy, and mixing entropy of carbon nanocones are proposed analytically. The optimal conform…
