English: Tensile test simulation movie for two different collagen densities: 1 mg/ml vs. 4 mg/ml. The collagen fiber geometry for this test simulation is random fiber network and deformed the simulation box from 0 strain to 0.5 strain, using a 0.01 strain step increment. Simulation box size is 200 µm (length) ×200 µm (width) ×300 µm (height). The top 50 µm and bottom 50 µm of the box is anchored area. All fiber-beads in the anchored area are fixed, and then the top anchored area is deformed to z-direction and the bottom anchored area is deformed to –z-direction. Each snapshot image in the movie is taken at the quasi-equilibrium state after each 0.01 strain step (1 µm to z at the top and 1 µm to -z at the bottom) was applied.
