The mechanical properties of cortical bone
Splet20. jun. 2024 · The mechanical properties of cortical bone were determined from 852 indents on two orthogonal cross-sectional surfaces. Mean elastic modulus ranged from 7.56±0.32 GPa up to 21.56±2.35 GPa, while mean hardness ranged from 0.28±0.057 GPa up to 0.84±0.072 GPa. SpletThe morphometric parameters used were indicators of bone mechanical properties, microarchitecture, and functional adaptation to loading history [112]. Descriptions for each parameter can be found in Table 2. ... procedure was necessary in order to facilitate a later step in the data collection process to ascertain subchondral bone cortical ...
