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.
