Analysis of pressure distribution in the foot using finite elements

Abstract

The objective of this study is to evaluate the applicability of the finite element method to analyze pressure distribution in the healthy human foot. Images of a foot were captured using computed tomography and converted into a three-dimensional model, which was adjusted with the aid of CAD software. The model was imported into Abaqus software for finite element analysis, considering the different regions of the foot. Observations of displacement, stresses, and pressure distribution demonstrated a biomechanical behavior of the foot consistent with that reported in the existing literature, regarding the regions of peak plantar pressure. These findings demonstrate the feasibility of evaluating the physical and mechanical behavior of the human foot using the finite element method, and can serve as a reference for the study and manufacture of orthotic appliances, prosthetic devices, and insoles.
