The aim of this project was to determine the load paths of a prosthetic socket using finite element analysis. This allows for the socket liner and frame geometries to be more accurately chosen. The socket analyzed was a medium length upper left leg socket.
The external forces where found for the leg. While the characteristics for socket loading were assumed. These enabled the socket stress distribution to be found. Allowing differences in socket and socket frame types to be observed. |

Fibreglass and polyethylene sockets, double socket frames and four types of fibreglass frames were analysed. The effect of both flexion and extension to alignment was assessed. Finally the materials between the loading and the socket were varied.
