Trabecular bone numerical homogenization with the use of buffer zone
The paper is devoted to calculation of effective orthotropic material parameters for trabecular bone tissue. The finite element method (FEM) numerical model of bone sample was created on the basis of micro-computed tomography (µCT) data. The buffer zone surrounding the tissue was created to apply the periodic boundary conditions. Numerical homogenization algorithm was implemented in FEM software and used to calculate the elasticity matrix coefficients of the considered bone sample.
