Nanomechanical Characterization of Canine Femur Bone for Strain Rate Sensitivity in the Quasistatic Range under Dry versus Wet Conditions

Table 1

Elastic modulus (GPa) and hardness (GPa) values averaged over six specimens for each condition (wet, dry) and/or loading/unloading rate (10, 100, and 1000 𝜇N/s) (mean ± standard deviation).

Condition	Loading rate (𝜇N/s)	Elastic modulus (GPa)	Hardness (GPa)
Dry	1000	24.5 ± 0.9	0.9 ± 0.1
Dry	100	22.6 ± 5.4	0.9 ± 0.2
Dry	10	22.2 ± 5.6	1 ± 0.3
Wet	1000	14 ± 4.5	0.6 ± 0.3
Wet	100	13 ± 4.7	0.67 ± 0.4
Wet	10	15 ± 5.9	1.1 ± 1
