纤维的机械网络在自然界和技术中以一系列尺度出现，从细胞的细胞骨架到血凝块，从纺织品和毡到皮肤和胶原组织。他们的集体反应取决于选民的个人反应。以及网络中的密度、拓扑结构和顺序。在这里，我们使用的例子，低密度的合成毡的无热长丝研究的通用功能，包括应变硬化和大的有效泊松比的这种网络的机械响应。一个简单的微观模型使我们能够解释我们观察到的这些特征，并为我们提供了一个基线框架来理解主动生物力学网络。
Mechanical networks of fibres arise on a range of scales in nature and technology, from the cytoskeleton of a cell to blood clots, from textiles and felts to skin and collageneous tissues. Their collective response is dependent on the individual response of the constituent. laments as well as density, topology and order in the network. Here, we use the example of a low-density synthetic felt of athermal filaments to study the generic features of the mechanical response of such networks including strain stiffening and large effective Poisson ratios. A simple microscopic model allows us to explain these features of our observations, and provides us with a baseline framework to understand active biomechanical networks.
