  • Title: Internal stresses, normal modes, and nonaffinity in three-dimensional biopolymer networks.
    Author: Huisman EM, Lubensky TC.
    Journal: Phys Rev Lett; 2011 Feb 25; 106(8):088301. PubMed ID: 21405605.
    Abstract:
    We numerically investigate deformations and modes of networks of semiflexible biopolymers as a function of crosslink coordination number z and strength of bending and stretching energies. In equilibrium filaments are under internal stress, and the networks exhibit shear rigidity below the Maxwell isostatic point. In contrast to two-dimensional networks, ours exhibit nonaffine bending-dominated response in all rigid states, including those near the maximum of z=4 when bending energies are less than stretching ones.
