Özet

In this work, it was aimed to examine the mechanical behaviours of femur bone under different boundary conditions, Young's Modulus and loads by using Finite Element Analysis. As a result of the analysis, femoral neck and femoral shaft were found the critical areas in the case of compression. Critical areas were differed by the boundary conditions. When the load was applied from distal femur, maximum stress occured at femoral neck. When the load was applied from femoral head, maximum stress arise from femoral shaft, especially around the screw hole. It was observed that stress rate was higher for larger screw hole and maximum stress occured around the 6.5 mm screw hole of which angle was 10 degree. Results stated that higher loading and lower Young's Modulus leaded to stress increment and larger deformation.
