English: Local deformation simulation movie for a random fiber network of 2 mg/ml (Figure 7). The test local deformed box (20 µm×20 µm×20 µm) is located at the center of the simulation box (300 µm×300 µm×300 µm). All beads in the test box are anchored and displaced in the z-direction with a 2 µm displacement step size for 30 steps. All beads are anchored and fixed in the outer layer of the simulation box (within 50 µm of all the box sides). Force vectors in test box, anchored layer, and internal box at quasi-equilibrium after each 2 µm displacement are separately presented in the top row. Note that the color bars indicate that the forces on anchored beads are in the order of nN, and those for the interior beads are in the order of pN. The bottom row shows the histograms of the forces in the test box, the anchored layer, and the internal box. Insets show magnified view of the tails of distribution at larger force values.
