Results from a set of micro-FE models of the laminar microarchitecture from the mid-periphery of the 4 quadrants of a normal monkey eye. Von Mises stress (a scalar measure of force per unit area) and maximum principal strain (local % stretch), sorted by magnitude, separated into 20 bins of equal volume, and plotted for the 4 micro-FE models from the 4 quadrants of the ONH. Stress and strain vary substantially within individual laminar beams, and by quadrant. Note that in this eye, the models predict that the stresses and strains are highest in the temporal quadrant of the lamina, and that the peak volumetric stress and strains are much higher in these micro-scale FE models than predicted in their parent macro-scale continuum FE models (approximately a factor of 4–5 larger).
