... environment. The test parameters were selected to simulate the hip prostheses loading conditions. When the cyclic fatigue load of 3.30/0.33 kN (742/74 1bf) was applied to the fatigue specimen [producing the maximum fatigue stress of approximately 524 MPa (76 ksi) through the center section of the fatigue...

..., with a smaller stress concentration factor for the sandwich specimens. To optimize the geometry of the miniature sandwich specimen with respect to stress concentrations, the influence of parameters such as tab material, thickness, and taper angle was investigated. A stress analysis was conducted to calculate...
