Calculation of the mechanical properties for lower limb below knee amputee using partial differential equation and finite element method

ABSTRACT

The theoretical based of real displacement forces exerted on the below knee for an amputee prosthetic are considered. Partial differential equation [PDE] in boundary condition surround of prosthetic is theoretically suggested in order to find forces components and stresses. The theoretical model is applied to simulate the prosthetic. The data of image segmentations are found to support the results obtained using bio-mechanics simulation. Furthermore, it is important to mention that the fitted socket to the underneath knee prosthetic should have a large safe margin with surround of soft tissue
