| Outline of Final Research Achievements |
We have developed a new manufacturing method for the material and models of bone, which is mainly made of polyurethane, it is for operation training for orthopaedic doctors. In the process of its manufacturing, the density of the porous foam can be changed, which leads to the control of the drilling property related to the mechanical behaviors of the material. In this study, to quantify the relationship between the pore distribution and the drilling properties, we evaluated the mechanical behaviors of the models by the push out screw test and torque test changing the pore density, and quantified characteristic properties. In addition, we evaluated the mechanical properties by using FEM/homogenization technique and availability of the modeling for the bone model with X-Ray Micro-CT was discussed. We found that the mechanical behaviors of the model can be controlled dominantly by the pore ratio and the micro structure.
