Abstract
⺠Indentation modulus of lamellar bone subject to nanoindentation tests decreases with the penetration depth. ⺠Contact stiffness decreases with decreasing indentation force upon unloading. ⺠We use a Continuum Damage model to predict the contact stiffness decrease on the unloading branches. ⺠Continuum Damage models can also predict the decrease of indentation modulus with increasing penetration depth. ⺠The nanoindentation experiments carried out at multiple penetration depths have been successfully simulated with finite element models.
