Abstract

The model of surface remodeling using a lattice continuum, a mechanical model of cancellous bone with trabccular architecture, is proposed to express changes in volume fraction and orientation of trabecular architecture of cancellous bone on the remodeling process. Nonuniformity of surface stress at the lattice member is considered as the microstructural mechanical stimulus activating the trabecular surface remodeling. Rates of change in the width, orientation and interval of lattice element are derived from the uniform stress hypothesis in terms of the effective normal and shear stresses and couple stresses at trabeculae. 1 Introduction In the case of cancellous bone, the
