Abstract
This paper is devoted to the microstructure geometric modeling and mechanical
properties computation of cancellous bone. The microstructure of the cancellous bone
determines its mechanical properties and a precise geometric modeling of this structure is
important to predict the material properties. Based on the microscopic observation, a new
microstructural unit cell model is established by introducing the Schwarz surface in this
paper. And this model is very close to the real microstructure and satisfies the main
biological characteristics of cancellous bone. By using the unit cell model, the multiscale
analysis method is newly applied to predict the mechanical properties of cancellous bone.
The effective stiffness parameters are calculated by the up-scaling multi-scale analysis.
And the distribution of microscopic stress in cancellous bone is determined through the
down-scaling procedure. In addition, the effect of porosity on the stiffness parameters is
also investigated. The predictive mechanical properties are in good agreement with the
available experimental results, which verifies the applicability of the proposed unit cell
model and the validness of the multiscale analysis method to predict the mechanical
properties of cancellous bone.
