Research On The 3-Dimensional Finite Element Modeling Of Human Foot-Skeleton Based On CT Images

The thesis presents an experimental case study and the result in applying Finite Element Analysis method in biomechanical engineering. The case is about human foot, a complex skeleton-muscle system. First, the thesis discussed the necessity and the significance of the 3-dimensional modeling of foot-skeleton. Then, it analyzed the main problems in the 3-D Finite Element Modeling of human foot-skeleton based on CT images with the thickness of 2mm, in view that foot-skeleton is complex in geometry and small in size, and composed of large quantity of bones and joints. It was introduced the approach of the 3-D Finite Element Modeling of human foot-skeleton, which includes the reconstruction of foot-skeleton based on CT images with the CAD software that is powerful in complex surface modeling, and CAE software for FE modeling. It was also described the treatment of cartilage and ligament for a more complete model. The model was analyzed with simulated clinical boundary condition and loading. The correlation between the computed results and the simulated clinical condition was discussed to verify the validity of the model. The conclusion and the perspective on future were given at the end.
