Abstract

Numerical and experimental stress analyses of bovine femur for determining the mechanical properties of calcium- phosphate ceramic as an artificial bone implant B. Ekici & S. Altintas Department of Mechanical Engineering, Bogazici University, 80815 Istanbul, Turkey ABSTRACT In the present work the stress distribution in a fresh cow femur is determined. The finite element method (FEM) is used for a three-dimensional model with 1500 degrees of freedom. Geometrical and material data are taken for this model from a cow femur. The same bone is used in the compression tests to determine mechanical properties and the results are compared with the calculations. The objective of this study is to improve the basic knowledge of the stress distribution in a whole femur and further to arrive at a general basis for some applications of ceramic bone implants. The FEM model has been used to study the influence of materi
