Maximum principal Green strain field on a representative axon in an initially isotropic fibre network (fibre volume concentration = 0.3) pulled transversely. Although the axon's shape follows the gross transverse displacement, the strain field is highly localized. The grey regions have strains out of the range of the colour bar. The panels on the right show the 2D slices viewed from the top. In the 2D images, the collagen fibres are colour coded based on their Green strain value.
