DESIGN & FEM ANALYSIS OF HIP IMPLANT FOR WALKING AND RUNNING LOADING CONDITIONS

Hip Joint is a ball and socket assembly formed by spherical head of the femur and concave acetabulum of the pelvis in the human body. A band of tissues called ligaments connect the ball to socket in order to provide stability to the joint. Hip joint transplantation and modification are common in old aged persons as well as younger persons. The loads acts on joint are repetitive and fluctuating depending on the activities of human being, which may leads to failure of Hip joint. Also the contact pressure developed due to fluctuating loads generates wear debris particles due to rubbing of contact surfaces. In the research study linear elastic finite element study is carried out to determine Stresses developed in Jumping Loading Condition. To evaluate the stresses developed in all these conditions and to come with best material suggestions
