3D model analysis of human foot

Abstract

In recent years, skeletal models of the human body are used to review biological structures and performances. The analysis of foot is of considerable interest, as it has physical interaction between the body and the surroundings throughout locomotion. Analysis will be vital for understanding the impact of mechanics during human standing and motion. It is difficult to directly measure the stresses on the foot. However, by using FEA, a 3D model of the foot is created from CT scan images and analyzed for stress and deformation using ANSYS. The distribution of stress within the foot model of human not only depends on the geometry but also on the structure and application of load on the foot. Using MIPAV software, a combined image was generated from CT scan segmented images.3-D model of the human foot was developed using ITK SNAP software. The complete 3D model of foot was generated and imported into ANSYS and meshed. Static structural analysis (load & deformation) was carried out in ANSYS at different loading conditions. The deformation and stresses of the human foot were evaluated at various static loading conditions. The results were used to study the biomechanics/design of human foot during gait cycle.
