ABSTRACT

Increasingly, musculoskeletal models of the human body are used as powerful tools to study biological structures. The lower limb, and in particular the foot, is of interest because it is the primary physical interaction between the body and the environment during locomotion. The goal of this paper is to adopt the powerful finite element (FE) modelling and analysis approaches to create a state-of-the-art 3D coupled foot-boot model for future studies on biomechanical investigation of stress injury mechanism, foot wear design and parachute landing fall simulation. In the modelling process, the foot-angle model with lower leg was developed first based on 2D medical images (CT images) using softwares of ScanIP (image processing software), Surfacer and ANSYS. Then, the boot was represented by assembling the FE models of upper, insole, midsole and outsole built based on the FE model of the foot-angle, and finally the coupled foot-boot model was generated by putting together the models of the lower limb and boot.
