Means and standard deviations of elastic properties of oim and Phospho1 tibiae embedded in PMMA, indented with a sphere in dry conditions. E’ is the plane strain modulus; G0 is the instantaneous shear modulus and G∞ corresponds to the shear modulus at infinite time; G∞/G0 represents the elastic fraction (viscous 0 ≤ G∞/G0 ≤ 1 elastic).
