Abstract: The objective of this study is to use the finite element (FE) method to predict the mechanical signals (interstitial fluid velocity, strain, pore pressure, and pore fluid velocity) produced by osteocyte during physiological activities. The model predicts that the amplitude and distribution of the mechanical signals are mainly affected by the loading rate. The magnitude of mechanical signals in the lacunar-canalicular system increases as the amplitude, frequency and amount of direction of load increase. Collagen hillocks can effectively amplify strain signals at the process. The established model can be used for studying the mechanism of bone mechanotransduction at the micro-level.
