本文给出了无热随机纤维网络在点力作用下产生的位移场（网络的绿色函数）。这个问题被定义在线性弹性的限制内，并且对于由各种参数集表征的非仿射网络，该领域被数值地获得。经典的绿色函数解决方案适用于距离点力大于阈值，这是独立的网络参数的范围内研究。在较小的距离，纤维相互作用的非局部性质修改的解决方案。
This article presents the displacement field produced by a point force acting on an athermal random fiber network (the Green function for the network). The problem is defined within the limits of linear elasticity, and the field is obtained numerically for nonaffine networks characterized by various parameter sets. The classical Green function solution applies at distances from the point force larger than a threshold which is independent of the network parameters in the range studied. At smaller distances, the nonlocal nature of fiber interactions modifies the solution.
