Design of the Artificial Bone Scaffolds Based on the Multi-field Coupling Model

The integration design approach for the Artificial Bone Scaffolds based on the Computer Aided Design (CAD), Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD) is developed, and the multi-field coupling Scaffolds Modelling process is proposed. In modelling process, the complicated bone scaffolds can be designed with CAD tools, and FEA and CFD are the tools to analyse the mechanical and internal micro circulation properties. The CAD tools present the geometries and internal microstructure of bone scaffolds, and then export the models to CFD and FEA tools for properties analysis, such as the stress and strain of the blood against the channels, the flow velocity of blood. Three partial models composed the whole design approach, namely activity model, technical system model, and the information model. A special design case on the artificial bone scaffolds model demonstrates that this integration approach can facilitate to build the multi-physics fields coupled bone scaffolds.
