The Effect of Material and Model Type on Behavior of Femur Bone under: Static, Modal and Dynamic Analysis

Three types of analysis are represented in this study for three intact finite element (FE) femur bones models with two material types. Static analysis studied stress distribution in intact femur bone under excessive load that was stumbling case (critical and dangerous load case). The dynamic load was assumed to be impact load and natural frequencies of FE models were calculated in order to specify the failure characteristic of bone in fractured mode. ANSYS workbench version .14 was used in these numerical analyses. The results represent the effect of changing material type where orthotropic material shows lower stresses values in both static and dynamic analysis with respect to isotropic material.
