On effective properties of heterogeneous bone scaffold

Scaffold material, porosity and internal pore architecture are essential parameters for bone scaffold design that affect both scaffold function and cell-tissue ingrowth. A general approach for design of bone scaffold is to mimic natural tissue properties, namely, the tissue heterogeneity and anisotropy. This paper presents a modified multi-cell model that can be used to predict the effective properties of heterogeneous bone scaffolds with an improved accuracy. Results from the model prediction are reported.
