Comparative Finite Element Analysis of Jaipur Foot and Polyurethane Foot

Abstract

FEA is amongst best methods that help users to solve complex problems. There are fixed number of nodes in each ele- ment of the model that define the element boundaries to which boundary condition and loads can be applied. The geo- metry of the structure, the load applications, stress and displacement gradients can be approximated in a accurate man- ner, if the mesh is finer. The problem with the foot was unusual cracks in JP Foot and early breakage of PU Foot due to crack propagation [1]. To solve this problem we modelled the foot using SolidWorks and performed FEA Analysis for single leg below knee amputee patients. After analysis, it has been concluded that JP Foot as compared to PU Foot has more stress bearing capacity but has less displacement threshold due to its material properties [2]. This work will lead to optimization of both the feet thus enhancing the durability of foot.
