Bone remodeling considering residual stress: preliminary experimental observation and theoretical model development M. Tanaka*, T. Adachi& & Y. Tomita& ^Faculty of Engineering Science, Osaka University, Toyonaka, Osaka 560, Japan Faculty of Engineering, Kobe University, Nada, Kobe 657, Japan ABSTRACT The residual stress in bone is probed experimentally, and a theoretical model is proposed for the bone remodeling considering the residual stress. Basic features of the proposed model are examined in comparison with the exper- imental observations. These results encourage the hypothesis introduced. INTRODUCTION Tissue growth and resorption by remodeling under changing mechanical en- vironment bring the nonuniform natural state. Due to the statically inde- terminacy, the residual stress remains in the tissues without external forces [1]. It is supposed that the residual stress may be a key to understand the functional adaptation by remodeling. There is experim
