iomechanics is the study of the structure and function of biological systems by means of the methods of mechanics. Finite
element analysis is a computer based numerical analysis method which can be used to calculate the response of a model to
a set of well-defined boundary conditions. Hip total prosthesis was used for the patients who has the hip fracture and unable to
recover naturally. To design highly durable prostheses one has to take into account the natural processes occurring in the bone.
In this paper, the static load analysis is based by selecting the peak load during the stumbling activity. Two different implant
materials have been selected to study appropriate material. The results showed the difference of maximum von Mises stress
and detected the fracture of the femur shaft for different model (Charnley and Osteal) implant with the extended finite element
method (X-FEM), and after the results of the numerical simulation of X-FEM for different was used in determining the stress
intensity factors (SIF) to identify the crack behavior implant materials for different crack length. It has been shown that the
maximum stress intensity factors were observed in the model of Charnley.
