我们研究了随机光纤网络的弹性。从非仿射形变场的微观图像出发，计算了标度理论和自洽有效介质理论中的宏观弹性模。通过将非亲和性与网络的低能激发(“软模”)联系起来，我们获得了纤维网络中存在的非仿射变形的详细表征。
We study the elasticity of random fiber networks. Starting from a microscopic picture of the nonaffine deformation fields, we calculate the macroscopic elastic moduli both in a scaling theory and a self-consistent effective medium theory. By relating nonaffinity to the low-energy excitations of the network ("floppy modes"), we achieve a detailed characterization of the nonaffine deformations present in fibrous networks.
