Mechanical properties of wild type (wt) and oim/oim bone obtained from experiments and simulations: (a) Toughness (rigorously, work to fracture in compression) calculated as area under stress strain curve obtained from micropillar tests; (b) The ratio of failure strain to yield strain as a measure of the degree of plastic deformation for micropillar specimens; (c) The ultimate strength in axial tensile tests at the cortical tissue scale; (d) The in situ nanoscratch toughness. In all plots, error bar represents standard deviation. The statistical significance was tested using t-test with p < 0.05.
