In this example the forces acting on a Femur with an implanted hip prosthesis are analyzed during a gait cycle. The used gait model is the GaitVaughan example, taken from the AnyBody Managed Model Repository. The forces are transferred to a Finite Element Model and stresses and strains are analyzed for the bone tissue and the hip prosthesis. The Finite Element analyses were conducted by our partner CADFEM using Ansys and the Any2Ans interface developed and distributed by Ozen Engineering. In part two of the Finite Element analysis load cases are compared
