论文摘要
我们考虑使用数值模拟和分析理论的组合，响应于点力的应用，响应于点力的应用，我们考虑了沿着半纤维细丝网络的特定细丝的张力的传播。我们发现网络中力的分布是高度异型的，少数纤维在围绕力施加点的多个网格尺寸的距离内支撑了大量的施加载荷。我们建议这些结构可能被认为是拉伸力链，我们通过模拟探索其结构。我们开发了对点力响应函数的自洽计算，并引入了转移矩阵方法，以探索张力（弯曲）能量的衰减和网络中拉伸力链的分支。
We consider the propagation of tension along specific filament of a semiflexible filament network in response to the application of a point force using a combination of numerical simulations and analytic theory. We find the distribution of force within the network is highly heterogenous, with a small number of fibers supporting a significant fraction of the applied load over distances of multiple mesh sizes surrounding the point of force application. We suggest that these structures may be thought of as tensile force chains, whose structure we explore via simulation. We develop self-consistent calculations of the point-force response function and introduce a transfer matrix approach to explore the decay of tension (into bending) energy and the branching of tensile force chains in the network.
