ABSTRACT
AA new total femoral prosthesis with composite structure was designed, and the femoral prostheses under static state were analyzed with ANSYS software (version 5.7). The effects of elastic modulus, Poisson's ratio and the ratio of the inner radius over the outer radius on the stress distribution were investigated. Through a comprehensive analysis of the experimental results of positive stress and shear stress on the prostheses, a new design of the femoral prosthesis was put forth as follows choose the composite materials of which the outer layer has low elastic modulus and great Poisson's ratio, the inner layer has enough mechanic capability, and the increase in the ratio of the inner radius over the outer radius is as great as possible.
